Disregard me, I'm wrong. I assumed that when they integrated Facebook and Twitter account settings into the main iOS system settings. They also created methods in the iOS SDK to pull up those login pages/handle the transitions to the those apps, if installed, but I'm wrong. I just looked it up and you still need the Facebook/Twitter SDKs to accomplish that. So like most numbers on that internet that one is made up.

I'd edit my comment if I could but it's been to long. Sorry about that.
