If you REALLY want to see the difference in speed between the iPhone 3G and the brand new shiny must have of the season iPhone 3G S you should check out this comparison video. It demos a particularly complex track in AirCoaster 3D, a roller coaster simulation application.
And then tell me honestly; can you REALLY wait another year before you upgrade to the iPhone 3G S?
Don’t lie to me.
I know you want it….
