I will being getting a Dx on Friday but my GD will get my Droid. It is rooted and has as 4.7. When I take it in to have it switched to her number at the store and the Dx put on my number will they need to look at my phone? If so should I revert back to stock? I am assuming all I need to is rsdlite back to 2.01 and let it update to 2.2 right?
