Does this phone give any visible signs you would be able to notice by just turning it on and making a few phone calls? More to the point... would the guys at best buy or radioshack be able to look at the phone and tell its been rooted by just turning it on and possibly making a few phone calls? The reason I'm asking is if I buy one out right.. and something happens within the first 30 days.. most stores take it back... not "no questions asked" but, they switch it out in store instead of forcing you to go through warranty. If I brick the phone and its my fault.. fair enough..but, if the stupid thing dies from being a faulty unit.. then.. I think its fair enough that they swap it out..
