How to speed up the iPhone 3g

I found a short video on the Tube, it seems that using the future release of the iOS you could gain speed with your iPhone 3g.

The first test shows how the iOS 4.1 is more performant while you want to send a new SMS message.

The second test shows the differences using the Map application, the reactivity of iOS 4.1 is fantastic.

Also the use of safari seems to give good performance.

I will try the new release as soon as it will be released, may be on the 8th of September.
