Ok, my iphone does not have a section to upgrade software, it just has about and usage , any suggestions??
The Software Update option only appears if you have iOS 5 or later. With older versions, you update using iTunes. But you cannot update your iPhone. iOS 4.2.1 is the latest version for the iPhone 3G.
An iPhone 3G or second generation iPod touch can't be updated past 4.2.1. A newer device running an iOS version prior to 5.0 must be updated from iTunes on a computer.
If you have an iPhone 3G with iOS 4.2.1 as indicated in your signature, you are already at the highest possible.
thanks for the info,
