On starting VeriChat I am getting an error message that says: could not open tunnel - Failed. What do I do?
You will need to configure your device to access the Internet directly without going through a corporate BES/MDS. You can do this if your carrier supports this. Detailed instructions on how to do this are at available on this page at the Blackberry Forums. In general, you will need to upgrade to atleast Blackberry OS v3.8 and then go to Options->TCP on your Blackberry and set the APN (and some other) fields correctly. BlackBerry Internet - MSN/chat/web/telnet/TCPIP - No BES!
Hope that helps, it worked for me
