Rooted Skyrocket needs to be sent to ATT - Faulty Screen

[y311ow]

Hi guys, here is the story. I have a rooted Skyrocket running CM9. Yesterday morning, the screen just went black. Can't see a thing. I can still receive calls, the phone is functional. Went to the AT&T store, they called their warranty department, and it was decided I'd be sent a refurbished Skyrocket. I have to send my old one in. I'm worried about my warranty being voided since I am rooted. Is this a valid concern? Will AT&T being able to determine if I am rooted with the screen not being functional? Is there a program I can use on my computer to view my screen so I can unroot my phone? Thanks in advance for your help.

I'm pretty sure. See vincom's thread over at xda to return to stock. That way you'll be all set
