I have posted this a few hours ago in the news forum on 4.2.1 but everyone was arguing about how many pages they could or could not open in Safari, rather than offering advice as MR used to be. Anyway, downloaded the update, iTunes said it was preparing for update and then I got Error2 and since then the phone has sat here with an Apple logo and and an empty bar on the screen, won't turn off and doesn't respond to iTunes. Any suggestions? I have unplugged the USB, changed the USB and restarted several times without anything changing. Thanks in advance.
