Invalid Tunnel

I received this email from a WeBuzz user and I wanted to share it with you.

I'm not sure if my BB 8120 is supported bcuz the version that I downloaded was installed successfully but I cannot register It keeps telling me invalid tunnel.

Hi,
Please make sure that you have a proper TCP connection.
Please Go to BlackBerry Options, clicked "Advanced," scrolled down to "TCP" and type in wap.voicestream.com if there was empty or ask your service provider for the proper TCP connection.

I hope this could help, please let me know if it works or you still have a problem.

Thanks,
WeBuzz Support Team
