I still have SR 10.2.1.2156 as my official OS on the Q10 above, but I've had SR 10.2.1.2977 for weeks on my unlocked ShopBlackberry purchased Z10. Will I receive an official update soon from T-Mobile on my carrier unlocked Q10, or must I go another route because it is now unlocked? Is T-Mobile still pushing out official updates for BlackBerry phones?
