I need help with iphone 3gs. Ok here is my problem....phone not powers when i press power button .....but when phone is up and running, power button works just fine.You can put phone to sleep,wake up, or power off. So to power it up i need to connect phone with usb cable,it powers automaticaly. and if usb cord connected, then i can power it of,and power back on with power button with no problem. Did Restore with itunes ,but no luck... Any ideas???? Thanks.
