Download iOS 4.2.1 and update in iTunes. If you're an unlocker preserve baseband using snowbreeze.

But I forgot to mention that my iPhone 3G is jailbroken. Can I update it in iTunes?

If you wish to update while jail broken its recommended to restore and update in iTunes. That will make you lose your jailbreak but you can jailbreak again easily
