Please keep us informed of any issues. The iPhone issue has to do with how we track your login, we are working to update this to work with mobile phones properly.
If you have any issue with the site dropping connection, kicking you out, etc please let us know. We are working on some very big things for the future and #1 is quality user experience.
Also, are you guys on Mac or PC? What browser do you use and are you getting any error code when you get booted?
