My iphone wont ring in sleep mode. I searched this forum and apple's forum and the only solution is to either open it up and mess with the wiring, or return it to apple. I have already sent an iphone to apple and the one i have now, which doesn't work, is the replacement they gave me, so i am pissed beyond words. My question is, I unlocked my iphone for tmobile with turbosim. If i restore could i be able to buy a prepaid att phone for the number and activation so i could send them the phone without them knowing i unlocked it? I didn't mess with the baseband or anything since i used turbo sim. At this point i just want my money back
