Lol! These are brilliant! My boyfriends phone has a similar thing and am constantly getting messages which make no sense; best 2 were "I feel sick, think it was the mistake" (milkshake) and "Important just with..." (I'm just with...)
I don't have an iPhone so have not had the pleasure of personally receiving one of these hilarious messages.
I had to get off the website I posted because I was laughing so much I nearly threw up :)
