Do I need to upgrade to 4.3.3 or 4.3.5 first before iOS 5? I thought with the ispw file on my desktop I could just upgrade from 4.2.1 manually but getting errors. It's upgrading directly via apple.itunes but I can't see what version it's downloading. Wondering if it's iOS 5 directly. Doesn't really matter since it's working but I'd like to do this manually. Thanks update: finished 4.2.1 to iOS 5 all in one swoop but I'm still wondering why I couldn't do it with the ipsw file. Anywhoo. .
