There are two ways of accessing Wellesley Google Apps services on your iOS devices.

1) For the quickest, easiest access to your Gmail, download the Gmail app from the App Store.

2) You can sync mail, calendar and contacts through iOS's native apps. Some advanced setup required.

Note: iOS devices will not sync all your calendars into the Calendar app. After syncing your calendar in the previous step, visit this website for customizing the view for multiple calendars on your iOS device. We recommend bookmarking it as the need for viewing different calendars arise and disappear.
