On your device, go to Options>Advanced Options>Host Routing Table. Press the menu key and select Register Now. Then, pull the battery and allow your device to restart. Let me know if that helps.
Now try to resend your service books. Go to Email settings>Press the menu key and select Service Books and select Send Service Books. See if that gets you going.
I click on that and it says: Select an email setup option. I want to use a work email account with a Blackberry Enterprise Server. and nothing else. If i click next it says"Has your Blackberry Enterprise Server administrator provided you with an Enterprise Activation Password?" I click yes and then next and put in my yahoo email and password and click activate and then it says" Activation request failed. A service connection is unavailable."
