Bloomberg has now posted an updated version (126.96.36.199) specifically for the 9630 Tour on their mobile site. This resolves the error. (Note: this application is only for subscribed Bloomberg Anywhere users.):
1. From your Tour, go to http://m.bloomberg.com
2. Select Blackberry
3. Scroll down to Bloomberg Anywhere and select Download
4. Scroll down to the 3rd installation link: Bloomberg on Blackberry 188.8.131.52 Compatible with 9630 Tour
If you already installed the previous version (184.108.40.206) this will upgrade without any trouble (i.e., no need to uninstall first) and you should not need your B-UNIT to authenticate again, but it does require a reboot. According to Bloomberg TS, they hope to have compatibility built into the next monthly release so you won't have to manually download.
