I am trying to activate my SIM for my new iPhone, but can't even get my PC to recognise it. I'm using Windows XP and when I first connected the USB, the installing hardware box came up but said it was unable to complete the installation. However, the bubble still came up in the toolbar that the new hardware was ready to use. So, I opened iTunes (have got the latest update), but still it didn't recognise my iPhone. I have checked the Apple Mobile Device is running in services.msc, and there seems to be no problem there. I can't understand why my PC won't install it, my iPod works fine so I'm baffled! I just connected my iPod to the same USB socket with the same cable, and it connected no problem at all. But as soon as I try to connect my iPhone the same way - nothing! I remember having this problem when I first installed my iPod a few years ago, but can't remember how I rectified it! Any help would be most appreciated.
