What's the latest iOS I can update to in an iPhone 3G??

The latest and last iOS for the 3G is iOS 4.2.1. That's jailbreakable using RedSn0w.

What do you think about whited00r?

 

[willerz2]

Whited00r is at your own risk. All it is is a UI change, there's no increase of app support outside of a very limited pool of apps, and is very unstable.
