I picked up 8G iPhone Friday evening and installed via iTunes. Got confirmation 5:30 am Saturday. Made a couple of calls and they got dropped. Oh well. Next noticed that clicking on keys has no sound and external speakers not working. Can't hear with or with out ear phones on ipod. If connect to wi-fi and go to utube, it will not play. If put in headset and redo utube it loads and plays with headset. What is goin on here. Must be a bad phone. Called Apple and they don't know what problem is. I have macbook and am using bootcamp with Vista and iTunes to set up iPhone. I went to the Apple store got new iPhone but keep same sim. Came home it works great, but drops calls and then no signal at all. Next iPhone goes into mystry mode exactlly like phine #1. Now I go to local ATT store and they give me new sim card, but phone has no signal in store, they said I need to redo iTunes again. OK. I redo iTunes and still in mystery mode as before and still no service. Help me please. On line with Apple as I type.
