As for everyone else complaining about battery life, THIS IS AN ALPHA BUILD. They've said time and time again that it's an issue. Either try reflashing, a different modem, a bigger battery, deal with it, or flash to something else and wait for an official release.
BTW, if you use Wifi a lot, it's actually worse than 3G on this ROM apparently. I'm getting anywhere from 12-16hrs on one charge with low/moderate use. Also, let your battery cycle through a few times before complaining about battery life.
I hope this helps someone
