If I sell my iPhone5, is there a way to clear my number off?

If I sell my iPhone 5, is there a way to remove where it says "your number is ___" and lists my old phone number? Or is a new phone number something the new user must configure?

I restored it to factory defaults so I could sell it, but it still lists my number in the contacts menu.

If you take the SIM card out (a little slot on the right side) it will no longer use your number

  • Is there any way I can sell my mobile app UI and graphics? Is there any way I can sell my iPhone app UI? I worked on an iPhone app project early this year but due to personal reason, I have no choice but to discontinue my project. The UI was designed by a very professional graphics designer. I haven't worked on the source code though, which is a good thing because I would have to spend a lot of money on the programming phase. Is there any website where I can sell my iPhone app UI without the source code?

  • Is there any Danger in Sharing your IMEI Number off your Phone? I'm selling my old iPhone as it's water damaged and just selling it for parts. Someone has requested to buy it and asked for the IMEI number. Just wondering if there's any danger in sharing this only through private message and also wondering why he would want it if the phone is broken.
