Simply changing the address the server connects to no longer works. That was a temporary fix while not all of the servers were upgraded. As of about 5pm pacific yesterday, the last of the servers were upgraded.

Someone had compiled 2.5.5 for maemo, and discussed it on a forum, after ICQ had changed. We can dig that up and compile 2.5.7. When that happens, we need to get the packages into the repository.
