CDMA users have had a fun time trying to get their hands on the latest BlackBerry software, but now they won’t have to resort to Rapidshare to get the new OS. The Canadian carrier MTS Mobility has OS 4.5 available for public download from RIM’s site. If you’re looking to try it out, just grab the file, install, make sure you have the latest Desktop Manager, and plug in your BlackBerry via miniUSB when it’s open. Don’t worry that it’s from another carrier, you should be fine after deleting the vendor.xml file on your computer. OS 4.5 features rich text e-mail viewing on supporting BlackBerry Enterprise Servers, among other goodies like a variety of attachment download capabilities and free/busy calendar lookup. Folks packing the BlackBerry 8830 World Edition might still be out of luck, although there are torrents out there for unreleased versions of the software. CDMA subscribers can head on over to RIM’s site to get upgrading their Pearls and Curves.
