I powered off my phone for a few minutes after it went to "No Service" from T-Mobile. When I went to turn it back on the silver apple appears for a few minutes but when 'updating circle' (not sure what to call it) comes on it covers have the apple and freezes. It will freeze like that for a couple minutes then it goes through the whole cycle all over again without me touching any buttons. I've tried holding down the home and power button at the same time to reboot and the same thing happens. And itunes won't recognize when its plugged in. Help would be greatly appreciated!!!
