Answer 1

Restore your phone to default settings.  

Answer 2

I would restore your phone to its default settings. The only problem with this is, that you will lose any downloads you may have and you will lose your contact list. It's really up to you. But before you default your phone, call your service provider and explain the situation you may be able to get some free stuff out of them for your problem :P

Answer 3

Maybe your phone number was secretly changed by your secret admirer so only he knows the real phone number. :]
