Here's a quick overview of my Android experience.
The TB is my 4th Andoid phone, and 4th phone that I've rooted (Eris, OG Droid, Incredible, now TB). In the past, I just rooted to access SetCPU and free WiFi tethering. Now I'm looking to go a step further and get some good battery life out of the stock 1400mah and ditch the bulky extended battery.
So what would someone recommend to flash that is AOSP Gingerbread, that has good battery life, without suffering in terms of capability? I'm on the most recent OTA update, running sense 2.1 and am fairly happy with that UI.
I'm already rooted and have Clockworkmod Recovery flashed to my device. Rom Manager is already installed as well.
