It’s a good sign that OS 5.0 is starting to move across carrier’s in North America. Yesterday both Sasktel and TELUS released OS 188.8.131.529 for the BlackBerry Tour 9630. It’s highly recommended if you have a Tour 9630 that you upgrade to this new OS. Follow the links below to download this OS, and remember your Tour 9630 doesn’t have to be from either of these carriers. Simply install the file and remove the vendor.xml file (more details here).
