Ok so I am currently running windows 7 64 bit and for some reason my iphone 4 can no longer be seen in my computer however sometimes it does but when it does it will not be seen in itunes. I am running itunes 10.2 and when I try to sync it with itunes it syncs just fine. However, whenever I try to restore it it would get stuck trying to restore it. The progress bar on my iphone would never move and I would end up unplugging it after 20 minutes with an iphone stuck in recovery mode. However, when I plug it into my laptop and restore it I can restore it just fine. It's obviously something with the drivers but I cant put my finger on it. Even weirder is I keep getting error codes and each error code is a completly different error code one was related to usb, one was related to windows but was never consistant. Anyone else experience the same issue with Iphones and windows 7 64 bit? Also I tried removing itunes and the drivers and same issue incase anyone was curious.
