I updated to 3.0 today on my 3g which I had canceled last month, It was just too slow without 3G and not much better when I used it in Orlando with 3G. so now it is basically a Ipod touch. It still let me update for free and it's much better now. I can still use it with wi-fi, the camera seems faster, safari is quicker, plus the best feature is I can play music or a podcast and then still use other apps such as safari and mail. Maybe if they ever get 3G in my area I might reactivate but for now it seems to run any app as long as I have a wi-fi connection, just no phone. I might jailbreak it later, does anybody know if you can do that without an active sim card?
