Title says it. I used win7 and winXp, it is being detected as iPhone but, there is always a problem on the driver. But as I go to troubleshooting, wherein it reinstall the driver, it suddenly works! But the problem goes back as I re-plug the iPhone on the computer. I tested other iPhone [my brother's 3gs] and it works perfectly fine. Added info: It charges iTunes detects it correctly [sync etc., I even did a restore] can any one please help? thank you!
