Those are awesome cases by Beyza Cases. I actually just emailed them last week with a request to come out with Roadline Series (flap) cases for the Bold. Similar to the ones that they currently have for the iPhone. Currently I use the OEM Premium Leather holster. Hopefully they come out with the Roadline Series cases for the Bold soon! Maybe it'll come out sooner if more requests are sent to them!
Edit: I just BBM'd the guy that the OP sold his bold to (traitor) and he confirmed with me that the Beyza case doesn't allow access to the headphone jack whilst the device is in it. ):
Well this is a perfect example of don't believe everything you read. My case does in fact allow access to the headphone jack. That's too bad if people made a decision based on this false information.
Also, mine took 3 days to arrive. I ordered late on a Monday night, it was scheduled for a Friday delivery, and came one day early. Not bad at all.
This case has been great for me. (Slimline for 8900 using with a 9700) It's a little looser than I wish. It slides out easily, but I can't get it out without pushing it from the bottom. So probably perfect by most people's standards. Overall, I'm very satisfied. Quality and craftsmanship is great.
