OOps. Just discovered something.
I am able to download the app. I am able to set up a gmail.com account.
I am NOT able to set up any of my q.com accounts. These are qwest accounts, they were serviced by Microsoft and are now going to be serviced by qwest. I have the updated info, however, once I set up the incoming info, the phone will connect and then K-9 force closes. Apparently the issue is with the q.com situation. Anyone else have this happening?
