My external speaker blew on my Evo, so I wanted to get it replaced. I didn't, however, want to be bothered putting the phone back to stock. I went into the store and they asked my name. I said well before I tell you my name, my phone is rooted, is that going to be a problem to get my speaker replced? They said no worries, we all have our phones rooted as well. They replaced the speaker with no issues. They did however want my Gmail account and password. I said there is no reason for you to have that information. They said we might need to do a reset on your phone. I said that is nuts, there is no reason to reset my phone for replacing a blown speaker. They didn't get my account information and the speaker was replaced, so all's well that end's well I guess. Just a bit of advice, you don't have to give them that personal information, especially for something as mundane as a speaker replacement.
