Why on earth is Facebook writing their own SSL layer for iOS?

SPDY (pre-Apple's version) + Open Source SSL Library + Perf Mods

I would guess one of NIH or SPDY. And they may not be (probably aren't is my guess) writing their own, just packaging one up that they know works with whatever depends on it.

Stock SSL on iOS doesn't have NPN, which is needed to negotiate SPDY on the internet.
