we on BlackBerryBase started a new over-the-air project.
You all know StormOTA. It is good, but not good enough ...
BBB:OTA is accessible by Desktop and by BlackBerry, via the desktop version you can add applications and themes, your comments to an application or theme. All the same things you can do via your BlackBerry.
The desktop version has got a feature which you only have on the desktop version: 20 random downloads (in the future they could be in a Cover Flow-ish design, hard to develop but our developer is on a good way).
Another point for BBB over StormOTA is, that BB is for the Bold, Curve and Storm. Not only one device.
It is only available in German, I don't think that this is a problem for you.
