My 3GS has operating system 4.2.1 on it, when you plug it into iTunes and check for a software update, it says you have the most current version of software available, now ive updated iTunes to ver 5 and i put the phone into DFU mode as well as just trying to update it the normal way and nothing works, any suggestions would be great thank you

Hey here's a thought...wasn't there like a 4.3.5 update in between your's and iOS5? Did you try that one or did iTunes default to iOS5?
