I’ve worked with a few user’s of BBTrackr to fix the Tunnel Failed error. If your on BIS you need to set your APN settings.
The value for your network can be found here:

To configured the TCP settings in BlackBerry as follows:
menu => Options – Advanced Options - TCP and enter APN information per the link above.
I hope this helps!
