I have only had the phone a few weeks, and overall it has been good, but the battery only lasts about 24-30 hours under moderate use, with push email, juice defender, and a few phone calls. So I ordered the Mugen battery and cover, direct from Mugen. Took about three weeks to show up, about $100. Fit and finish is better than expected, battery life on the first charge was three days. That will probably drop as I may leave more stuff on all the time. That is a Roots Phone Case RL1LBK. Sound is okay, but I just bought a Blueant T1 headset to go with it anyway. There is a bit of space inside the case going to waste. I'm thinking LED flash/light, inductive charger, magnetic plate/mount/holder.... Bonus: the camera lens is out of the way of your fingers and other objects, but is not obscured by the new back cover. I will melting or drilling a small pair of holes near the bottom of the cover to secure a lanyard. Using the hole at the top doesn't work for me and I always think the phone is the wrong way up.
