In response to upu1007, thank u for your response. &nbsp;When an incoming call comes in but the phone does not ring. &nbsp;Since I made the call from my landline thus I could see the light up and able to slide to answer the call. &nbsp;But I get strange sounds on the iPhone until the other side says something. &nbsp;<br />
Sorry for my ignorance, but where is the stand by button. &nbsp;I am not a power user of iPhone. <br />
Are there any other settings that I have to adjust. <br />
Thank u.

I have an Apple iPhone 3G and I just unlocked it and inserted a new SIM card from StraightTalk. &nbsp;It was working fine for a few days, but now when incoming calls come in, it gives me the option to Answer or Decline. &nbsp;<br />
How do I get rid of it and just let it ring as usual and then I answer. &nbsp;Sorry I lost in this iPhone technology and settings. &nbsp;Thank u.

The iPhone is a smartphone made by Apple Inc. It and the iPad, along with several other mobile devices from Apple, run on the iOS operating system, which has its own topic, as does the iPad for device-specific questions. Native iOS applications are written in Objective-C or in Swift using the Cocoa Touch frameworks or HTML5 compiled with the help of a package manager such as Adobe PhoneGap; a common IDE is Xcode.

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
