Gotta love the fact smaller carriers roll out OS release faster then the larger ones. One would think the larger carriers would want their customer on the latest given their install base. But, method to the madness I suppose. MTS Mobility has released OS 18.104.22.1689 for the BlackBerry Tour 9630, previously we have seen this as a leaked version so if you have this installed already you'll have no need to reinstall it. If you were waiting for an official carrier release, have at it just remember to delete the vendor.xml file if MTS is not your carrier.
