Hello all, I wanted to update my iPhone 4 to iOS 5 this morning, so I plugged my phone in and hit update. I hadn't updated in a while so the newest version iTunes found was iOS 4.3.5. I realized I still had iTunes 10.4.x and downloaded iTunes 10.5.0.142 from the apple website. I confirmed I was running the new iTunes, plugged my phone back in and tried to update, but got the message "This version of the iphone software (4.3.5) is the current version". What do I need to do to update to iOS 5?
