look what i googled:
default lionheart. with sio.
For some reason smartassv2 would reboot on me when i charge my phone :T as OP says it's still broken :x.
I used to like lulzactivev2 but like smartassv2, it doesnt' clock down when screen is on. I'd switch to those once they're active. but lionheart is pretty good.
