I have the Motorola MB522 (“Charm”) in operation. This phone has been working better for GPS tracking. It enables GPS lock more rapidly than the last phone. It supports Echolink fairly well. It is faster and more robust. The keyboard is very nice. However, be careful with grease. Grease can migrate underneath the keyboard and interfere with operation.
The phone is running Android 2.1. This is more than sufficient for me.
