Seen on a lifehacker.net comment: Version 1.5 doesn’t work with Google Apps, however it is possible to get version 1.1.1 working just fine.
* Browse to ‘gmail.com/app/v1.0.0/en/gmail-g.jar’ and download the version 1.0 client
* Enter your login information (your username should be your full Google Apps email address, i.e. [e-mail-adresse]
* You will get an error after the client tries to pull up the inbox. Just exit out of the application.
* Now go and download v1.1.1 by browsing to: gmail.com/app/v1.1.1/L1/ gmail-g.jar
* After it installs select ‘Keep existing data’ on your phone when prompted
* Now when you start up gmail it will use the saved login credentials from the previous install and work just dandy It’s completely ridiculous that they won’t support Google Apps, there doesn’t seem to be any technical reason for it meh.
