Yes open the MMS (picture message) and hit menu key. Scroll down to "forward" then your address book will pop up. If you want to take a picture message and forward it to someone using email select "forward as" then use your email from there. Welcome to CB.
I click on "forward" and this this is what shows up:

OOHHH, Sprint is different. I know there for a while people were complaining about not having MMS at all. Then just got it recently. I'm sorry I cant help you with that one since I am not familiar with sprint. Some one else will chime in and help you out rather quickly.
