MobilityDigest have a handy trick for selecting the maximum connection speed your Nokia Lumia 900 should use to connect to AT&Tâ€™s network.
This may be useful if you want to eke out the last bit of battery life from the phone in an emergency, or if you are in a poor signal area and your phone is wasting battery life flipping from one connection speed to another.
The instructions should be easier to follow with some screen shots, which can be seen at MobilityDigest here.
