While my phone was plugged into my computer and downloading the update, I had to go run out and do errands. When I returned, iTunes said the update had failed (or something like that?) and the phone displayed that it wanted to be connected to iTunes. Except it didn't see the phone, so I restarted my computer. And even after reinstalling iTunes, the situation is as follows: 1. If my phone is plugged in, iTunes will not start. 2. If my phone is not plugged in, iTunes will start but will not see the phone when I do plug it in. So... I'm stuck without a phone. How exactly do I force it to update?
