like others i had intermitant connections issues with my holux and freedom pucks with 8320 . well i can confirm that 4.5 os fixes all these issues. i drove from dc to manhattan and did not lose a bt connection once using nav4all and amaze...so rim has fixed this issue

ok, can you give us a little more info on how you got os 4.5 on that 8320 and where I can get it?

NO, the OP cannot.

He probably got it at the gittin' place. That's where you get things.

And, unfortunately, this is not "the gittin place" for unreleased OS's.
