I just thought I would drop by to say that there are two ROMs running Cornerstone up on XDA. I'm not sure how the mods view linking to other forums, so I'll let you look it up yourself, but I will say that Jermaine151's AOKP ROM is working great for me right now. I also tried the EOS with Cornerstone, but it didn't seem nearly as stable or smooth. Plus, it did some wacky stuff to my CWM Recovery that I have had to fix via ADB, which is a headache.
