My Blackberry won't send emails?

Question

I have a Blackberry Curve 8310 model and i've been trying to send a picture to my e-mail from the Blackberry but it takes forever and then it says 'error unknown' and it fails to send. It's worked fine before so what's wrong with it now? Please help. Thanks.

Answer 1

take the battery out for 2 minutes, then put it back in. My nephew has this exact phone, & has to do this once every two weeks!!!!! It's like rebooting your computer!!!!!!!!
