The only improvement I am hearing on all the forums is the iphone is snappier. This is because the Iphone reboots after the update. My iphone on 1.0.1 is very snappy and does not crash often because I reboot it every morning. The avg person probably has not rebooted recently and after the update they feel their iphone is snappier. Most of my friends don't even know how to reboot the iphone. I think Apple put out a real placebo here. What I want to hear is " I live in the bay area and before the update my Iphone would switch from EDGE to 3G to EDGE to even no service at times. Now after the update I get 3g most of the time just like the rest of my 3g phones." Come on Apple fix your 3g.
