Iphone no more charging

[topher004]

Well i had no problem with my iphone (3gs - 32gb)
But since i formatted my pc, i could no more detect it on my pc..
(it keeps saying unknown device)
I thought it was my usb driver, but it's not the case since i can use my pendrive, wireless mouse/keyboard, netgear and speaker(usb port) without problem.. And which is weird is that sometimes(not always well let's say really really rarely) it detects the phone! Thus i was forced to charge with the socket.

But today i could not even charge it with my socket :-S

I was thinking the port where i put my usb cable(below the iphone) was out of order now.
But when i switch off the phone and connect it to my pc - i just saw the apple logo - switch on (without that i touch anything) but not charging...

I don't know what's going on with this phone..

Help please :-S

I can't return it to the apple store, since it's someone from another country who sent this phone to me!

I had the same problem with my iPod touch, at the end I discovered that the problem was with the cable it self after reporting it to apple.

Did you reinstall iTunes?

Thanks for quick reply guys.
Yes i re-installed itunes (twice)
I even re-downloaded the setup to test.
@Jahrami did your ipod just turn on(without charging) when you connect it to your pc?(if it's switch off) I hope it's the cable. But i don't think, since each i connect it, my pc detect an unknown device.
