All the new devices like the BlackBerry Z10, Q5 and the BB Q10 are getting the BB OS 10.2.1 update starting yesterday which introduced a host of new improvements including an unlock of the built-in FM Radio tuner.
The update is already available to some versions of the BB Z10 and Q10. We tested it out on our own units — the BB Q10 (SQN100-3) got the update right away while the BB Z10 (STL100-1) got the 10.2.0 update which is 445MB, then another update placed it to 10.2.1 as well.
The other BB Z10 (STL100-3) have yet to receive them and is still at 10.1. This is the US unit we bought from BB.com last Cyber Monday for just $199.
The 10.2.1 update is about 644MB in size and takes some time to install.
The roll-out is quite gradual so some units might not get the updates as early as the others.
