I got rid of 188.8.131.520.
I was sick of it always going in EDGE mode, and it locked up all the time.
Also, dialing from homescreen always defaulted to the work phone number instead of the mobile number. Very annoying.
I wish they would go back to the original keylock sequence. I always end up pushing the mute button while putting the phone in my pocket, which deactivates the keylock and ultimately calls everyone. I'd rather have to push star+talk like before. Anyone know of a way to fix this on the more recent versions?
