I have my 1G iPod touch with the older 412MHz processor. Since I wanted to make it as usable as possible for the time being, I jailbroke it on 3.1.3. To my surprise, it seems faster now! The swiping between pages of apps seems smooth and when I quit and app to go back to the home screen, i actually get an animation much more now instead of just a flash to my icons. Anyone else notice this?
