Where has AT&T said any updates were coming. The rumors you are so tired of hearing about are coming from this forum and wishful thinking, nothing from AT&T. If you're tired of your SIII then by all means move on.
I bought my phone from Best Buy. When I was restoring my apps from the "My Library" section on the store, I installed the same AT&T VVM app that was on my Sky Rocket. It is working as designed.
