So I've been using OMFGB and CM7 for about a month now, and the other day I flashed Savaged Zen's GB ROM and I LOVE IT! It's faster than any other GB ROM i've tried and battery life is great! Keeping BT and wifi on all the time, OC'd at 1113mhz and moderate usage, I'm getting about 27 hrs and that's still with about 10% left but I swap batteries. Everthing seems to work except 4g of course, but these guys did an awesome job. I def recommend!
