Official 22.214.171.1247 OS released for Curve 8530 by Metro PCS
For those of us rocking the 8530, OS updates seem to be few and far between, but here's a little something to get you excited. Special thanks to @RystNet for the tip, it looks like Metro PCS has officially released 126.96.36.1997 for the BlackBerry Curve 8530. I haven't seen much about this OS yet, but official releases will usually treat you pretty well, having passed carrier testing. You can check out the discussion on it in the forums thread below, if you still want to do a little more research.
