Just like so many other Canadian carriers: Bell, Virgin, SaskTel, WIND and TELUS, MTS has pushed through the upgrade to OS 7.1 for the BlackBerry Bold 9900 and Torch 9810. If you have either of these devices you can upgrade OTA or via the desktop manager – it’s OS version 126.96.36.1997 and brings a few key features, namely the Wi-Fi hotspot. Remember to back up your 9900 or 9810 before upgrading.
Update: BlackBerry Curve 9360/9350 users can also upgrade to OS v188.8.131.528.
