I had berrymeter on my last 3 BBs...I loved that you could roll over it and it would tell you how many hours you had left on your battery. I don't see that it is compatible with the 9930. You guys know of a battery app that has that feature? I came close with BatteryPlus, it has a talk time/Standby time left...in minutes....am I being too picky
I installed some apps that aren't compatible yet with the device. To my surprise they all work flawlessly on BB7. I really like meterberry...give it a shot.
