Hello, So I still haven't updated. I thought I would wait to see what everyone thought about firmware 3.0 first. What I want to know is (setting all the new features aside), how is the responsiveness of the new firmware? I remember during WWDC, they indicated it would be faster than 2.2.1 due to optimization. Is it? How is the battery life, any better? What about the carrier signal. Do you get more bars now? Just thought I would put it out there to see what people's thoughts were on the new firmware. I have a iphone 3G.
