Default [Q] Some questions

Hi,
I have Xperia M but I seriously think about buying M2
Before this happens, I need to know a few things:

1. M2 has APP2SD support?
2. In M2 I can't pull up battery, am i right? If i have bootloop or something in Xperia M i pull up battery and flash ftf. How it works here?
3. GPS works fine? In M some users have troubles with GPS.

M2 is my little dream
