Hi, I've been trying to upgrade my iphone software because I have an app that says I need to upgrade it. The instructions on the apple website say "just plug in your iphone! It will upgrade itself!" But it doesn't do that. iTunes says "A newer version of iPhone software is available (version4.2) but when I click the update button it just says I have the current version of iTunes (?!) when I am looking to update the phone! I have Mac OS X, Version 10.4.11 iTunes 9.2.1 iPhone iOS 4.1 Any help would be appreciated!
