I hate how if I'm typing someone's name (that's in my address book) with an 's' on the end, the auto correct doesn't automatically capitalize it for me.
For example. If I'm typing "I'll meet you at jesseys" I expect it to change "jesseys" to "Jessey's" automatically but it doesn't. So, I usually type "jessey", hit space, then delete and type 's on the end of his name.
Hehe... my post is the only post that is constructive enough to stay.
