I'm sure once I find out how to fix it I will feel silly not thinking of it beforehand. For some reason the phone is not auto-correcting the word "I" when I text "i" it doesn't auto-capitalize. I checked to make sure the auto-capitalize function was enabled, and to make sure I didn't accidentally add "i" to my custom word list. Any ideas? If this helps I noticed it didn't auto-cap a state name yesterday as well.
