3.1 is a little buggy. A few hours after setting up Go Launcher I turned the screen on and the launcher had reset itself. I reinstalled the rom and set up my google accounts. A few minutes ago I launched the market and a window came up, saying I needed to set up a google account. Somehow my accounts got deleted.
First off, if you want to get the battery life back, drain down to 0, charge up to 100% and then reset the battery statistics in recovery, worked wonders for me.
Secondly, every one and a while i'll turn the display off with the power button, and it'll lock like that, and i have to bull the battery to get it to boot up again.
Also, the comments within the official facebook app can never load, it'll just tell you you dont have a connection.
Finally, in the Liquid settings/goodies/propmodder/3g speed hack, it'll work for me but wont survive the reboot, and when i boot the phone back up i have to turn it off to get service.
