It's been a really long time since the BlackBerry Storm 2 9550 saw an OS update. I mean, a REALLY long time. Well that streak has ended as forums member lyricidal let us know that Appalachian Wireless has officially released OS 188.8.131.522. It's available to download from the link below, so dust off Desktop Manager and give it a go! Of course, be sure to back up your data before you load it and if Appalachian Wireless is not your carrier you'll need to delete the vendor.xml file. Let us know in the comments or in the forums what changes you find!
