Not really much in there that we didn't know already, but its nice to see that the issue is making news. I cant see Apple ignoring this much longer - especially as the big pitch of the 3.0 firmware and 3gs were improved battery life.
To be fair though, 3.1 seems to have increased my battery life by about 25%
Yeah, I knew it was something we've all heard before, but it's nice to know it's making headlines. My phone overheats sometimes when I use certain GPS based apps, and the battery drains fairly quickly.
