To the handful of STL-1 users out there, 10.2.1.1259 has finally surfaced for you, courtesy of BerryOutsider.
It has been a while since 10.2.1.1055 made us all late to work, so if you have already experienced that build, there are not many more new goodies to see in this build so far. As far as we can tell there is only an added disclaimer that appears the first time you install an Android APK asking you to make double sure you know what you are doing before you proceed. The remember app also got a minor update that now lets you switch from notes view or folders view, which is nice for some people, but other than that, it seems like there are a lot of fine tuning in the core OS.
So without further ado, download BlackBerry OS 10.2.1.1259 for STL-1 here.
