Ramble worked fine on my BlackBerry 7105t until a few days ago when I started getting this error message when trying to log in:

"Invalid connection string: Bad DNS Address"

I configured Ramble according to the instructions at ramble-im:

Cellular Plan: T-Mobile Blackberry Unlimited Plan
Options -> Ramble IM -> Network Connection: Device Default
Options -> Ramble IM -> TOC Host & Port: toc.oscar.aol.com:1290
TCP Configured (Yes/No): Yes

APN: wap.voicestream.com
Username: phone number (or blank)
Password: T-mobile website password (or blank)

I tried to enter my username and password, but got a different error message.

Any suggestions would be much appreciated.

Thanks!

Have you tried pulling the battery on the BB and letting it reboot?

leave user and password blank

Thanks! Rebooting got it to work.
