I was just curious if anyone had tried the 1400mAh Mugen battery in a Pre 2 yet.

I was wondering:

1) If it fits and works

2) With the battery life enhancements on the Pre2 and WebOS 2.0, how long can you go on the Pre 2 with a 1400mAh battery?

I am interested in getting a Pre2 from HP but first I want to know if I can go the whole day without fiddling with turning off the GPS/Data etc.
