Signals been dead steady for me. Battery seems 'better' but the statistics reporting is still pretty messed up.
Unfortunately I'm not able to get GPS on the nightlies... running 4/26 at the moment and can't get a lock at all. Back on the 4/15 build I believe it was, with sbrissens fix applied, I could get a lock in my house within 3 seconds, all the way down to like 4 meters accuracy. Now I can stand outside on a clear day and nothing. It's as if the fix was not applied at all and it's back to the old ways of not locking on ever =/ just constant blinking GPS icon in the notification bar.
