Informal Testing Suggests Minor Performance Increase for iPhone 3G on iOS 4.1

Late last week, Lifehacker posted a video comparison of the performance of iOS 4.0 and iOS 4.1 on an iPhone 3G.

The video demonstrates the results, but here they are in all their glory:

- Messages: iOS 4.1 Wins (By a Little)
- Maps: iOS 4.1 Wins (By a Lot)
- Photos: iOS 4.1 Wins (Just Barely)
- Safari: iOS 4.1 Wins (Just Barely)

While the speed advantages ranged from marginal to significant, iOS 4.1 clearly outperformed iOS 4.0. It's still significantly slower performance than you'll get from a 3GS or iPhone 4, and we're still not sure it's a big enough improvement that 3G owners will want to ditch iOS 3. The most obvious difference was UI responsiveness. The UI didn't get stuck nearly as much on an interface element or when trying to enter text. If you are set on using iOS 4, the upgrade is worthwhile for that alone.

In late July, Apple acknowledged that it was looking into reports of performance problems for the iPhone 3G under iOS 4.0, and Apple CEO Steve Jobs confirmed late last month in an email to a customer that a software update addressing the issuing was forthcoming.

At last week's media event, Jobs announced the release of iOS 4.1 set for this week, noting the iPhone 3G performance issue as one of the bugs addressed in the update.
