It looks like the latest leak of OS 184.108.40.2061 for the BlackBerry Tour 9630 contained a new version of BlackBerry Messenger 220.127.116.11. From what I can tell the team at CentroBB spotted it and then BBHybrids took it from there. They have extracted the desktop install and created an OTA install out of it to make things easier.
