I have an iPhone 3GS with Firmware 4.0.1. It is so outdated that I can't hardly download any new apps. I've decided I just want to update my phone to the newest Firmware and not worry about it being jailbroke anymore. But I don't want to lose my contacts and basic information. I'm not worried about my apps, just the basic contact info, preferably my text messages, notes, and things like that. Is there a way to update my phone then put this information back on my phone? Thanks for anyone's help in advance!
