I have to agree battery life has increased by quite a bit. My wife was getting severely pissed off at this phone because of battery life and other Froyo glitches and since updating she has yet to have any issues and stopped complaining about battery drain. Ahh the relief of not having to hear about how she hates the phone and wants it replaced Now lol. Hopefully we get to see ICS eventually, not that I am counting on it anytime in the near future and most likely not at all but still it's a nice thought lol.
