Excellent review, John! My Freedom Mini is currently winging it's way across the Atlantic even as I type. I should have it soon. I am having a problem loading v.54 of TeleNav to my 8300...actually switching service from my previous 8800 to the 8300 to be exact...so I might have to talk to tech support on Monday.
But...from what you wrote, I am really looking forward to once again having GPS functionality on my BlackBerry. Plus, the keyring-friendly size is great too.
