I'm still on the ancient 2.3.9 Froyo leak from years ago, and though I've been meaning to get back into the Android scene, I've been really busy, so I haven't kept up with all the leaks (2.3.13, 2.3.15). I was wondering how to upgrade to the OTA update (2.3.15, I think) -- not the official one, but rather just its guts/kernel. I've taken a look around and there are a number of custom ROMs, but I assume that trying to flash them on my older kernel will probably result in a brick. Can someone link me to the (preferably rooted) OTA update for me so I can get in on some custom ROM goodness? Thanks.
