Yes, I woke up to news of the update and installed it right away. There are a couple nice new features, but a couple of my bigger issues are not resolved yet. Nevertheless, having a new update feels nice and gives me hope that RIM is working on all this stuff.
Update: a new version of BB Bridge came out this afternoon for my Curve. I installed it and found that The bridge browser is now working for me (before it was not). I also had a chance to test tethering and this is also working again.
This is BIG progress, because these were my two biggest problems with the PB.
The guys at work are going to be so jealous now! Thanks RIM!!!
