I have an iphone, that has been acting weird. It mostly started with this ( http://discussions.apple.com/thread.jspa?threadID=1146083&tstart=0 ), and now my iphone problem has grew. Safari/iPod crashes more than ever, and I just got a call from someone, so I slid the bar, and the bar froze, THEN the call answered, but the other end didnt hear me, with the screen still showing the persons picture. It then turned on the speaker, and a few seconds after that, the other line hung up. ALSO when i put the phone on the hold/sleep mode and go to turn on, the lock screen doesnt appear, instead what appears is the last screen I saw before I put it to sleep. And when I watch some videos, the sound works, but the screen is entirely black, as if it is turned off. I have restored it numerous times.
Nah, you are not the only one. Many have had issues like this, best bet would be to talk to the genius bar at your nearest apple store. If no dice, try apple tech support and have them send you a loaner while they check the phone out.
