Nokia 6126 / 6131 / 6133

Flashing to the newest unbranded firmware (6.10) is a *MUST* for a 6133. The T-Mobile branded firmware cripples this great phone way too much. Enough to mention the horrible battery life with the T-Mo firmware. Not sure what they did with this phone, but the T-Mo guys should probably take coding classes somewhere. Frequent crashes also a plague with their firmware. Anyway, you get the idea. After I got my 6133 flashed to 6.10 I easily get several days of battery life with moderate use (I used to get maybe 1 day before!) and no crashes. Still using this phone as my primary. You get the idea.
