Ahh, BlackBerry 10.2.1. For many it has brought a ton of welcomed changes and features to BlackBerry 10 that were missing from previous releases but for a good many others out there it has brought noting but frustration and anger. BlackBerry 10.2.1 went official on Jan 28th and while a lot of carriers released it the day it was announced, there's still a lot out there that have yet to make it available to their customers.

Some very prominent carriers such as AT&T state they're still testing the OS or that it's already been released, while T-Mobile hasn't said much of anything aside from conflicted reports from customer service reps who say it's already available and others who say they've heard nothing about it at all and Verizon, well no one really knows because realistically, they actually started the roll out seemingly by mistake a day ahead of the actual announcement. Sprint can't even muster a response it seems.

In Europe though, it seems most carriers have already pushed the update in one form or another with some even releasing a higher version then what was initially announced. The same has happened in Canada. Canadian carriers such as Rogers, Bell, TELUS and their various subsidies have all managed to release an update or two by now so it really does seem the majority of those remaining are simply U.S. carriers.

Keeping track of all the carriers that have and have not released the OS update is a bit of a daunting task, in part due to the fact that some folks on carriers ostensibly noted to not have released the update HAVE actually received it through various ways, be it after a device wipe or simply by connecting their device to BlackBerry Link. A lot of folks using unlocked devices also have received updates on carriers known to not have released the update and overall, there appears to be no rhyme or reason to the roll out pattern.

For those who have not received the update, there is a number of things to try such as wiping your device, connecting it to BlackBerry Link, checking for updates without your SIM card in your device and for those who REALLY want the update, you can always use one of the autoloaders from the CrackBerry Forums or use Sachesi to perform the update yourself manually. But, not everyone is comfortable with going through such measures for something that should be readily available from every carrier.

With all of that in mind, we figured we'd at least try to crowd source some idea of which carriers have not actually released a BlackBerry 10.2.1 update yet. If you're making use of a carrier purchased BlackBerry 10 smartphone and have not received the update, let us know in the comments. To be fair, this update seems to of have actually been one of the better rollouts of an OS for BlackBerry but alas, that doesn't mean a whole hell of a lot to those still waiting.
