I want to update my iPad from 4.2.1 to 5.1.1 but I have a problem. My iPad is jail broken, and I have downloaded the software for the iPad (iOS 5.1.1), but every time I try to update it via iTunes, it tries to contact apples servers. I am using a dial up connection as my router broke, and iTunes cannot get to apples server because dial up is rubbish. When I update, I hold down SHIFT while clicking restore. A file browser pops up and I click the Ipsw file (iOS 5.1.1) then it unpacks the file in iTunes and it tries to contact apples servers. It stays on that forever and I am unable to bypass this? Can you guys help me out? Thanks.
