I have an iPhone 3GS with a version of iOS that dates back to November 2011 (the version prior to icloud). I will update the OS once I have undertaken a few tasks on the phone.
Upon a recent sync with my iMac (after 6 months of non-syncing), 25% of my contacts were changed. In fact, a lot of rubbish contacts that I deleted FROM the phone have now been copied back to the phone from the iMac.
I often prefer my phone to be the master keeper of all things and overwrite what is on my computer when syncing. I need to now the following:
1. How can I delete all the contacts from my phone so that I can download a fresh version which I have synced with an app called Contacts Keeper where it stored all my contacts in Drop box.
2. How can I then ensure that the "fresh version" on my iphone then overwrites the version in my iTunes account on my iMac?
