Ok found a thread a few days back that was listing top five apps for this and that... had a problem with the email client that came with the DX wasn't letting me send email (even after talking with my IProvider about my settings) so I tried K9. Two questions..1. how do i stop the email client that came with the phone from recieving emails 2. when i had an email with K9 that had an attachment K9 wouldn't show it, came up with the error "Unable to find viewer for application/octet-stream" the email that came with phone is able to read it. thanks in advance for any responses
