For about the last 6 months or so, when I connect to itunes with my phone to do any upgrades etc.. The system tells me to do the upgrade, however when I run the 30 or 40min. upgrade at the very end it comes up with the same error message and the upgrade doesn't work. Prior to this I never had any trouble upgrading my phone. How do I get past this?
Well i have the same problem as well
