Up until now, each newly leaked OS upgrade for the BlackBerry Storm was for either the 9500 model, or the 9530 specifically. Now comes the next unofficial OS fix, 4.07.0.90 and it is designed for both models. So far here in the States, Verizon has seen fit to put its official stamp on the .75 OS which was even sent out as an OTA firmware upgrade to owners of the 9530. Early reports say that the accelerometer works better, a full QWERTY keyboard is now an option in portrait mode, and the phone seems zippier overall. Again, we caution you that this is not an official release and anything can happen if you take the risk to download it. Having said that, let's hear from some Storm owners who took the plunge. Is .90 the best OS build yet?
