Updating the OS does nothing to the vendor branding. All of the code is written by RIM and it is tested and released by the carrier. You can run any code released by any vendor and it doesn't impact what YOUR carrier pushes down.
Well I want it to look and act as much like a Tmobile phone as possible. She's got Tmobile now with a nokia she hates, she uses myfaves (so the myfaves interface would be nice to see on the BB Pearl).
So it sounds like if I unlock the Tmobile theme from the OS(or use the TMO OS update? is that enough?), switch to that and have the myFaves re-pushed from her tmobile account it should be good to go.
