My texts I send are always green...sent one just now & it was blue. Does that mean anything?
If the messages (and the Send button) are blue, you're chatting over iMessage with another iOS 5 user.
If they are green, you are using standard SMS text messaging.
Your device will automatically detect this and send whichever way is appropriate.
Blue means the message was sent as an iMessage. See p. 66 of the manual... http://manuals.info.apple.com/en_US/iphone_user_guide.pdf
