Screw that, I would go back and have her fix it. I also have never heard of the apps being xferred over, they typically go back to migrate (unload and re-load) your contacts and such. Other than that, I'd raise hell.. at this day in age you want to use any ammunition you have to fight for the service you pay for. In this case, she did NOT give you the Droid X "out of the box" the way she should have.
That said tho, LauncherPro is the shiznit... may be just as easy to keep it instead of paying for it.. or if in the case she somehow moved it over and you don't have to pay for another license form your Eris.. all the same. Good luck.
