i just upgraded my iphone 3gs to ios 6 not sure if it updated but now when i turn on my phone it says automatically that i need to connect it to itunes using the USB port but when i connect it it comes up as new hardware and cannot find a program/software for my device even though i have the latest itunes on my computer. i have tried reinstalling itunes but it still cannot find my phone and now i cannot use my phone as it is stuck on the sync to itunes screen
