If you never managed to install OS 10.2.1.2228, your patience has kind of sort of been rewarded as a new OS update has popped up in the CrackBerry Forums thanks to toobs623 and Wigley458. This time around, it's just a small update covering a few system files that look to improve NFC and the Settings app but hey, it's newer so it just might be worth the download.
It's hard to say what other improvements may be in this OS but you can head on into the CrackBerry Forums to find the autoloader download links, as well discuss any other changes you might be seeing after you have it loaded.
Keep in mind; autoloaders wipe your device clean so if you're not wanting to do that then you'll have to look at updating through Sachesi. Finally, if NONE of this makes any sense to you, then it may be best to just stick with the OS you have or ask in the forums for further help on getting it all loaded up.
