I showed another eris user my rooted phone, and she was "Do that to my phone" so i rooted it and another friend mentioned it voiding your warranty, and she got all sad.."what did you do to my phone?"i have insurance..blah blah blah. whatever. i made it better and she still has a warranty in my eyes. you only need to trade in a phone thats broken. you cant tell if a phone is rooted if it is broken.
Just tell her you can always / also return it back to stock (i.e., un-root it) if she wants...simple flash of erisuser1's Flashback2.1 ROM: [ROM][10/20/2010]FlashBack21 v1 -Return to Factory Stock - UPDATED - xda-developers
She can't have it both ways.
