My problem: My 8310 will not standby/lock when it is holstered.
What I've tried: The obvious, Options > Security > General Settings > Lock Upon Holstering = Yes. I will put it in the holster wait a good 30 seconds - 1 minute, then push on the holster to hit a letter and see if the address book opens up and it does (from my understanding it shouldn't if locked) My guess is maybe I just have a junk holster (it is magnetic) or maybe something with the battery...
I have searched and just couldn't find much, this forum is great and full of knowledge so figured i'd give it a shot..
