So you were NOT at a corporate store?
Been there, done that *sprint store* I talked to the manager, I emailed everyone I could... yep got nothing, and my story EASILY rivals yours...
I am surprised YOU WERE not able to talk to a supervisor... you gave up THAT easy, I would have DEMANDED and demanded until the CS rep had no choice... that was a sham... you were placed on hold and the Rep was probably just sitting there... that was unacceptable.
Sometimes our time is the cost for service also =( ; we would think the process would be a breeze...
Sadly I left palm; user since Robotics Palm Pilot; left att (glad of that though);
THE USA is just not GSM/UNLOCKED phone friendly (sorry, never tried T-Mobile).
I await a flagship WebOS phone... in the meanwhile...
