It appears SaskTel is one of the first carriers to release an official 5.0 OS for the BlackBerry Tour 9630. While this doesn’t mean that any other carriers are any closer to releasing an official 5.0 update for the 9630, it is a good sign that carriers are starting to find builds which they trust and feel comfortable putting out for the consumers. No word on the quality or issues in this build. If you know what you are doing and feel comfortable enough go ahead and load this os. If you do, please be sure to share your results.
UPDATE: It was brought to my attention that MTS Mobility had already released OS 220.127.116.119 for the Tour. I missed this story..oops!
