How do I update my iphone 3G firmware 4.2.1 to 4.3.5?
I can't get some apps on my 3GS iphone because it has the IOS 4.2.1 and the apps need the 4.3.5
I can I update this iphone? Please help!!
iPhone 3GS, iOS 4.2
Sorry, but if you have an iPhone 3G, you cannot. iOS 4.2.1 is the final version an iPhone 3G can run. Confirm your actual model of iPhone here:

and if you have a 3GS - your post is contradictory, mentioning both the 3G and 3GS, post back and we'll go from there.
