I had the same thing happen to my 40 gig a few months ago. It ended up getting YLOD but was repairable. Still, I bought a PS3 slim and sold the broken 40 gig to a guy who was willing to fix it. Sorry I don't have any real advise besides cleaning it out but worst case scenario you get YLOD like I did. Oh, and the slim is a lot quieter, I swear I sometimes forget to turn it off due to not being able to hear it.
I have tried to get the new mobile site to load on my iTouch (3g) with the 4.1iOS but the full site keeps appearing instead. I tried m.giantbomb.com and that didn't seem to work, anyone else having this problem?
