With the release of iPhone 4 and the new OS only a few days away, I upgraded my iPhone 3Gs to the latest Beta release of iOS 4. It is no surprise if I say that the new OS is great. The usage experience feels much smoother, and maybe a little faster. I’m sure there is a lot more hidden in the OS than I have had the chance to discover, but the multitasking is smooth and the new folders are just sweet.
