for some reason when I try to e-mail I get a "No message services configured". It directs my to the set-up wizard wich tells me it can't continue because of an error. nothing was wrong until about three days ago. My e-mail has been set up for quite some time. help? I have a 9700 bold t-mobile. 18 months old and fine until now. running os6. no apps except the one touch flashlight trial version that I have had for a long time. Thanks

Have you tried ....

a battery pull with the device turned on?
resending your Service Books?
re-registering your Host Routing Table?

If none of MM's suggestions work, call T-Mobile. They may have borked your provisioning and "forgot" you have a BlackBerry data plan. They did it to me once.
