I left GB it was just to old, it was smooth, and great but I missed all of the newer features and GB my battery actually wasent that great, so now I'm the latest cm nightly, I wish I could flash cm beta 4 but my power button does not seem to want to work on that ROM, it really sucks...
what do you mean that your power button doesn't work?
Also... keep in mind that the last time you had gb on your phone... the battery was also brand new. When you installed ics or jb out already had a year wear on it.
