For those of you still rockin’ an old BlackBerry Curve 8900 or Curve 8520, good news! Today, Magenta has officially released BlackBerry OS 22.214.171.1242 for both devices. The OS Upgrade is available online for download on T-Mobile’s site here. Honestly, I never thought I’d see another OS upgrade for the BlackBerry Curve 8900 but heck, better late than never right? Now all we need is OS 6.0 for the BlackBerry Bold 9700. Do let us know any changes you’ve noticed with the new OS in the comments!
