The latest OS leak, OS 5.0.0.190, delivers native threaded SMS for BlackBerry. While you won't get the tabbed browsing as seen in previous OS 5 leaks, the native SMS client is reason enough to download. But remember, as with all OS leaks, proceed with caution! Always back up your device first because you may lose data.
