Hello everyone I hope someone can help me here I am out of options. So I have the iPhone 3GS with the 4.3 software. Well my phone or actually any iPhone, iPod touch I plug to my computer do not work. I plug them in, automatically I get a message on the iPhone saying the devise is not supported and can not be charged, iTunes tries to grab it, but 3 seconds later the computer kicks it out and I get an iTunes message saying that the iPhone could not be found because the hard disk on the devise could not be found. And if I leave it plugged in the process just goes on and on. I've tried the following and none have worked: Re installed intunes-5 xs Updated USB drivers Updated iPhone Restored iPhone Updated iTunes/drivers Erased photo cache from iPhone Unistalled mobile devise-lost count Reset the settings on iPhone to og Restarted computer and iPhone many times while conducting any of these steps. Non work Now phone works fine because I can plug and sync with other laptops just fine. But my computer at home does not want to work with the phone. Can any anybody help please!!
