I'm using 2g iphone.
After upgrading to OS 3.0 the problems starts, before that, my iphone was working on OS 2.2.1 perfectly.
first, my battery gave me problems charging it, it did charge after plugging again and again to the electricity in the wall. half a battery took like 6 hours, after being fully charged, it wont charge again.
PC/Itunes wont recognize it at all since installing OS 3.0
i tried holding the power button + home button for 7,8,9,10 and even more for each try.
I tried different computer (Windows XP)

**Also, when I press the home/power buttons after the phone is off, the apple icon appears almost immediately.

I think i tried everything, working on it for the past week with no success.

Please help me out.
Thanks.

Sorry for my English, I'm not from the States.
