If your phone is Java-enabled, you can use the fast, installable Gmail application. To download the free Gmail for mobile application, visit m.google.com/mail from your mobile browser. Then, launch the application with the red "M" icon () from your mobile phone home screen or from the applications folder. If you also have a personal @gmail.com account, you can add it to this application so you can access both Gmail and Google Apps email accounts from the same place.

If your phone doesn't use Java, you may still be able to run Gmail as a web application. Visit mail.google.com/a/example.com on your phone's web browser, but remember to replace "example.com" in this address with your actual domain name.

Google Calendar

Depending on the model of your phone, you may be able to run Google Calendar as a web application. Visit calendar.google.com/a/example.com from your phone's web browser, but remember to replace "example.com" in this address with your actual domain name.

Alternatively, you can check your calendar, add events and get appointment reminders with text messages. Learn more about how this works here, here and here.

Google Docs

Depending on the model of your phone, you may be able to access Google Docs from your phone's web browser. Just visit docs.google.com/a/example.com, but remember to replace "example.com" in this address with your actual domain name.
