I bought my iPhone Friday at the (LAS) local Apple store, and Saturday morning began to use it. At first it was working OK, but my reception in my home was poor. My Motorola Q was much better in this regard, but I hoped it might get better. That day, I played with my new toy and noted that the speaker stopped working and other unusual things started to happen. If I went to utube, it would say "can not play this video...delete or Keep?" If I tried to play a song in ipod, the slider would move as the song played, but no sound from the speakers. If I put the earbuds in, utube would now play and I could hear the key clicks, the ipod songs and all sounds. What is going on here! My phone began to say "No Service" and If I did a reset, I would get a few bars, but it would not search for a signal if it went again into the No Service mode. I took it back to the Apple store and got another iPhone. Next day the exact, I mean the exact same symptoms began again. I thought that I had given my iPhone a virus or something. I spent hours and hours on the phone with Apple and ATT. I went to the ATT store and got a second sim card, still no help. I took this phone back and now I have a phone that works. I realized last night that there had to be something unique to me, my house, my car or something that is causing this dilemma. I thought that it might be the magnet in my case flap since the speakers were the first to go, as most speakers are some sort of magnet. So I did not use my case on the new phone and it seems to work OK. This could be a major coincidence, but I doubt it. So I recommend you do NOT get a case with any magnets in it. Funny thing is that I bought my case form "Everything Q" store for my Motorola Q and it never caused any problems!
