Same software? No. But a lot of the features that aren't hardware dependent could quite likely migrate into the Storm 1. For example, the QWERTY keyboard in portrait mode has been around for quite some time - if you're running a modern release it should be there in your settings.
Actually, the full QWERTY only came about with .148 unless the person was using a leak.
Depends on the carrier. I'm pretty sure it was in .132 as well, but since the OP has a 9530 on T-Mobile they're ALL leaks and I'd probably go with .151 if he hasn't upgraded in a while
