I'm 41 years old and I teach at school. I've owned black iPhone 4 since day 1 and find it indispensable, esp. for teachers. Alas, yesterday I dropped it in the toilet bowl full of poo. Do you think they will allow me to exchange it for the white iPhone 4 since it's still within warranty? Also, should I tell 'em the truth as to why it's not working? Any other tricks I can play to make them give me the white one? Please, advise.
