I posted a topic about this in the main forum but nothing has helped.... so earlier today the 'slide to unlock' feature doesnt work and when I shut off my phone and have access to the main screen again, the bottom 4 dock buttons dont work. Basically the bottom section of the screen does not work for some reason. I have tried turning it off/on....didnt work I have tried doing a soft reset...didnt work I just synched it so hopefully if I have to exchange it all my stuff is backed up....but that leads me to my next issue...if I take it to an Apple store for exchange, how is that going to work? I also havent used my $100 credit yet and I have read that there is complications when using an exchanged phone ughh! Someone please help me out, I cant even make calls!
