I have some friends using BlackBerrys who in the recent weeks started getting red X when they go to send emails, as well as (I think) SMS and BBMs.
This is happening to at least 3-4 people with different BlackBerry phones and not all on the same carrier. They call the carrier for support and they want to walk them through all the stupid stuff most BB people do to troubleshoot.
If anyone has any suggestions I am all ears.
