I am trying to help one of my friends. He made a backup from his old iPhone using ITunes. Then when he bought his new I phone 7 the tried to restore the data from the backup but it received an error saying "backup is corrupted ".

Any idea what to do at this point ?  is there any tool that can fix the corrupted backup.  The old phone is gone i can't not create another backup. The only available backup we have is the one that says corrupted.

Thank you,

How can a user's contacts contained on an iPhone be backed up?

This user doesn't want to use iTunes for the backup so what other options can be used?

I'm currently looking at building a small basic app that a few of my customers are looking for, however they all want it as their own unique app so I will need to whitelabel each release from one core set of code, instead of managing several different sets of code / apps.

All companies will have the exact same app features (which are very basic), however I will need to change the 'logo', 'app name' and 'main UI color' for each release.

Swift / iOS and Android Studio seem to have their own 'Whitelabel Management' feature so that you can have one code base and release variable releases from the code base.

So, you build one core app, and then you can release different builds with the variable settings.

01 - Has anyone ever used this approach before, and if so do you have any advice?
02 - Is anyone aware of any software (outside of Swift and Android Studio) that will manage code like this, as I might go the Hybrid approach with React Native.

Thank you in advance for your help.

I have a user with iPhone 5E and iOS version 10.2.1.

I am trying to add an email (Exchange 2007) to her iphone but it keeps showing certificate not trusted. I have tested the same email account on another iphone with same iOS version but different model and it works okay. I have deleted the account and re-added it but no success.

When adding an account on her phone, it says "cannot verify server identity" but error is caused by the certificate not trusted error.

Please see the attached. There isn't even a menu Trust at the top.
Is there a tracking app so another user can tell location of IPhone?
I have the situation where my 3 Mac computer all sync text shortcuts perfectly. My iPhone can receives text replacements made on my Macs, but if I create one on my iPhone, the other devices don't get it.  It's like the other devices have a 2-way street between them, but my iPhone has a one way ( incoming ) street only.
I want to map FROM the windows 10 to the mac how can i do this ?

Good afternoon; have noticed something that's affecting multiple iPhones in our organization. As noted we're a Exchange 365 shop and are using iOS devices with the latest OS; our clients all use the Mail app for their company Exchange mail.

The issue is this: sometimes when a user types in a name of a company employee, and that employee is not in their contacts, or in their 'recent addresses' cache, the iPhone will locate and display the entry from the global address list in a few moments. Other times, with other names, it never returns a hit from the global address list. So some names work, some don't.

To make it more confusing, if you type in a name it doesn't return a hit on, and after a moment, hit the backspace key twice (to shorten the last name) it then instantly finds the entry in the GAL.

My suspicion is that shorter names are found very quickly and partial last names also return hits faster than a full name; I noticed that if the full last name is short, it also seems to return an answer faster.

Curious to hear if others experience this and if it's consistent for you, and also for any insight.
Is there a way to capture a web page on an iOS device  so that any links on the webpage remain live.

What I’m doing right now is hitting the share button, selecting print,  selecting the printer,  and then reverse pinching, then hitting the share button again and saying open in PDFpen Pro which then stores it in iCloud. I WOULD REALLY LOVE A WAY TO AUTOMATE THAT PROCESS.

 I am able to get the webpage but the links are no longer live.  The files get stored in iCloud and then on a weekly basis I drag-and-drop them to be ORCd and filed.

Do you know of an app that will capture the page as a PDF that will keep the Links live.

I am looking at DevonThink to go but it seems overly complicated and difficult to search. Not sure where it stores the database but it does allow you to save as a WebArchive

Having an issue with Outlook on IOS devices (iMac, iPhone and iPad) prompting for passwords.  Latest OS and Outlook updates installed.  Appriver hosted exchange account.

When accessing the account on one device it logs the others out.  If the person is in Outlook on their iMac then goes to their iPhone the iPhone asks for a password and after putting it in it will work.  But upon going back to the iMac it will ask for a password.  It does this across all three devices.

It seems to have started doing this after a password change.  We have deleted all keychain references, removed the account and recreated it and of course rebooted everything.  We even tried changing the password back to the original to see if it made a difference and it didn't.

Thanks for your assistance.
I have a web app which takes data from a form submission POST and calls some php, passing the data to it.
Once the php call is completed successfully, the page redirects to a thank you page.

I've placed a gif in a DIV on the page and set it to hidden and written two simple javascripts to unhide the gif when the form is submitted and rehide it when the page loads. This works perfectly on PC based browesers, but does not work on any browser app installed on an Iphone or IPad.

Is it possible to get this working on IOS without having to re-invent the bicycle? Thanks
Hello all,

I am looking for an all-in-one home security system that combines the following features:
- WiFi (I'm tired of the limitations with wired cameras)
- Cameras (minimum 720p) - minimum 4 channel
- Sensors (door/windows)
- App controllable from anywhere
- Compatible with Google Home and/or Apple Home App

So far, this is all that I've found. It's probably not a perfect fit but I am going to contact the manufacturer.

- Fuers FW1 Wireless WIFI + Telephone Line Home/House Burglar Alarm System

Acceptable compromise
- Two separate systems that work with Google Home / Apple Home App

Thank you :)
If you keep the mobile phones safe in your pocket or purse, it's still at risk for picking up a virus or leaking data to thieves. Hackers don't need physical access to your phone to steal your personal information or infect the device with malware. They infiltrate your phone with innocent-looking apps or link to it via unsecured Wi-Fi networks. A Technology blogging site ( ) talking about this problem. Before some days I take my new phone from online shopping site ( Some informative site ( ) also provide disadvantage of hacking. Now I want to know how can protect my mobile phone from being hacked?
I'm trying to reduce the amount of space consumed by iPhone Mail.  I once remembered there was a setting to limit the amount of emailed download from the server either in terms of number of emails or overall total size of mailbox (I'm. It referring to individual mail).  

I cannot seem to find those settings anymore.
We have an Exchange 2013 setup ussing self signed certificates, everything is setup as pretty much bog standard with the exception of mailbox sizes being allowed more than default.

OWA and Mobile access works and 90% of our IPhones work, we have a few that don't.

On the majority of our Iphones when we add the exchange account it comes up with image 1 - Image 1 has 3 buttons and allows us to press details and trust the certificate - once we press details and trust it works.

Image 1: click details and accept
Image 2 shows what a few of our devices do, the continue button is missing and the details button just shows us the certificate with no option to trust it, All of our devices are running the latest ios 10.3.2 and the ones that haven't worked have even had factory resets to see if it resolves the issue.

Any ideas would be appreciated.


Good day fellow experts,

Since us Canadians are still awaiting on a Cortana iOS arrival (just checked again for the umptenth time to be sure), I was wondering what you guys would suggest for a iOS/Windows 10 substitution.

Something that allows me to do the following:
  • Send/receiving texts/iMessages on Windows 10 to/from my phone
  • Easily sync reminders between iOS and Windows 10
  • Other neat things promised by the Cortana iOS app

I've tried the iCloud desktop app for Windows, but the Outlook plug-in didn't deliver to the degree that I was hoping.

I've also been following the Cortana Archives as well as this guy's post but nothing in the past while has been hinting towards Cortana arriving in Canada on iOS anytime soon.
I am a deaf individual and have never been able to use the telephone efficiently due to the fact that I need to lipread.  I sometimes hear snippets of the conversation, but not reliably enough to conduct a professional conversation.  I am not the only one in this boat either.

Over the years I have tried assisted typing services and even voice recognition apps, but I am yet to find anything that works effectively.  Last year I obtained a small grant and put this into the development of an Android voice recognition app, but unfortunately it didn't work very well and I ran out of funding.  I was dealing with an Indian firm and I think they were using an off the shelf online service to process the speech, which was very unreliable and led to unacceptable delays in the processed text appearing on screen.  It was clear to me after this experience that I need to work with experts in the field to stand a chance of success.

I've been toying with the idea of setting up a crowdfunding project to help develop an app that can overcome the obstacles faced by millions of deaf people.  But first It would be helpful to obtain opinions from voice recognition experts, for instance, what is the current state of play in the field?  What limitations are we going to face?  What sort of money are looking at?  Obviously I'm going to need to quantify the whole process before I can put it before the crowd funders or investors.  

I'd love to find any interested experts I can work with towards …
I have a website which incorporates a spinner/loader gif using js from an onsubmit action on a form.
The post action reloads the same page which processes the on post and redirects using location after server side processing.

On any PC based browser, the gif works as expected (becomes visible on form submission, runs until server side processing finishes)
On IOS, the gif appears to not load (tried on Chrome and Safari on iPhone 6s, updated). However, If I hit the back button on the ios browser, the old page appears <u>with the gif visible.</u> Code is below.

<!DOCTYPE html>
<html xmlns="">

<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />

<link rel='stylesheet' href='/style.css' type="text/css" media="all" />
    ...include phps;...

<script type="text/javascript">
function spinner() {
	document.getElementById('loader').style.visibility = 'visible';

function spinneroff() {
	document.getElementById('loader').style.visibility = 'visible';


<body class="bodygradient" onunload="spinneroff();">

We are concerned with using the latest Chrome due to data loss/leakage
via whatsapp sidebar : does this feature enable files upload/downloading?

is there any way to remove/disable it & how to go about doing this?

If it's a data loss risk & not possible to disable, which previous latest
version of Chrome doesn't have this sidebar?  I'm thinking of using
the older version & hopefully Google still release patches for it

I just thought that since Whatsapp on my Android allows us to attach
files, this feature in Chrome may allow the same

Hi I am new to Xamarin IOS, I am planning to develop application But I want to learn , how I can have database connection ? Please help for same.
Hi all,

I'm using Visual Studio 2017, cordova to deploy to ios, using html canvas and a facebook plugin. Apart a lot of messing around I have the code convert into an xcode project and i can open it. I have not been able to compile it to an emulator or device due to the following issue.

xcode is raising errors that weak references are no longer supported, and as far as i can tell cordova and/or facebook plugin are riddled with these. I had tried to enable Weak References in Manual Retain Release, and setting deployment target to ios 8.0 (lowest i can go), but it still throws the error:

Apple LLVM 8.1 Error
-fobjc-weak is not supported on the current deployment target

The only link i have been able to find is the following and nothing on that page works:

I have updated cordova, all plugins and all programs like remotebuild to the latest version where possible.

I do not know how to use a mac, nor do i understand xcode. I would simply like to compile the app and eventually put it on the app store. Can anyone point me in the right direction on what I can do to make the weak reference error go away?

hi hope you are well.

i have a customer who wants me to lock down his apple devices, 3 phones and 4 ipads.

he wants me to prevent him from being able to access certain types of adult websites and proxy sure you can guess what i mean.

i was planning to use Trend iwsaas, which creates a vpn , which is really good at this kind of thing, unfortunately, he can simply turn it off in settings, and there seems to be no way to prevent him from doing this.  iwsaas can even block keywords in url's , enforce google safe search etc. so i can put "proxy" and "vpn" in the blocked keywords list, as well as actual web addresses.  

im looking into mdm but all i can seem to find are very expensive products for enterprise.

ideally id like to be able to configure and maintain this remotely or over the phone because he is geographically an hour or so away from me.

anybody got any ideas as to what i can do please?
Ever since we updated from Exchange 2010 to Exchange 2016 all our Mac Mail users are unable to connect to the exchange server.
OWA works on those computers HTTPS://   But it will not work within the Mac Mail Program itself.
