This is the most bizarre bug I've seen yet. Trying to respond to an email message on my iphone. As soon as I type the word "facebook" in the message the mail app freezes. I've tried several different messages and I've tried typing it in different parts of different sentences and as soon as I hit the letter "k" the mail app freezes. My only guess is that it has something to do with the suggested words/autocomplete/spell correct but this is as bizarre as it gets.
