So my girlfriend has a blackberry Curve 8300 i believe. She can receive emails but when so go's to send one it gives here a red X. Her email is setup right as far as we know and shes had the thing for over a year now and it's never done this. I've heard that re sending service books works but she said she did that and it did nothing. Also I told her to re validate her email in email setup but it still doesn't work. Help! Unfortunately I'm not near her to check it out myself.
