MTS Mobility 

*Update: Looks like the issue has been fixed. The download page now shows OS for the Storm 9530. *

In what looked to be another official OS, MTS Mobility has dropped OS -- but it appears to be for the Storm 9500, NOT the 9530. At first glance it seems like 9530 all the way, but as you can clearly see, the filename is "9500" (I installed the OS on my PC to verify). As MTS Mobility is a CDMA carrier, we're not really sure who is to blame for the mix up. The forums lit up with the good news of a 9530 release, only to be let down upon further inspection. We'll try to figure out just what gives and report back. Until then, if you are a 9530 user, do not try to install this OS on your device :-)
