So I finally decided to take the plunge and upgraded my original to the 3G over the weekend. Interestingly, the 3G model with OS2.2 seems more responsive than the original iPhone. I am not talking about the internet bandwidth--obviously that is faster because the network is faster--I am talking about the responsiveness of the OS and apps themselves. I did a "restore from backup" on the new phone, so my apps, preferences and configuration is also the same (lessening the chance that this is a simple 'reformat speedup'). How is this possible? I thought that the 3G had exactly the same underclocked hardware as the first model, with an almost identical firmware image (save for the 3G modem baseband) and that the 2nd iPod touch contained a newer, far more powerful CPU/VPU chipset (not only a newer part, but less underclocked as well). Hence, the original and the 3G should be absolutely identical in performance, right? What gives?
