Well, just took a quick roadtrip for the first time with 4.2.1.109, and sure enough the bluetooth GPS still hangs intermittently.

So I'm wondering, is this a straight up software problem, or is there some hardware element to this? I'm so frustrated with my complete inability to use bluetooth GPS for reliable navigating on my 8100 pearl, that I'd be willing to swap it out for a new 8100 if there is any chance of a hardware swap fixing it.

Or am I SOL until 4.5 comes out?

How can blackberry screw up something as fundamental as bluetooth? Arrg! lol
