I just noticed mine today too. The build date on my phone is Jan 15, 2009.

I think I a couple of days shy of the 30 days. I was wonder if it's worth getting the phone replaced. I think mine happened after I was on the phone for a while. I noticed the phone was getting pretty hot. While I was on the phone, I had it propped on my shoulder against my face. I didn't think the pressure was much. I did put a crap load of smudges from my oily face. I was thinking it's from the combination of heat plus prolonged pressure. Maybe the the amount of force, but the constant pressure.

Anyway, I noticed it today at work under the light.

Also, are you guys going through the self service page on Sprint.com, calling, or the store to get this replaced? Also, what are you saying to get it replaced besides the rainbow/oil slick?

Thank you.
