How to setup Gmail on iPhone and iPad

If you would rather use the native mail application on your device rather than the Gmail app for the iPhone and iPad this is a quick guide to setting it up.
Using the native email app  has many advantages such as easily managing multiple accounts.

Open the Settings application on your device's home screen.

Open Mail, Contacts, Calendars.

Press Add Account....

Select Microsoft Exchange.

In the Email field, enter your full Google Account email address.

Leave the Domain field blank.

Enter your full Google Account email address as the Username.

Enter your Google Account password as the Password.

Tap Next at the top of your screen.

Choose Cancel if the Unable to Verify Certificate dialogue appears.

When the new Server field appears, enter m.google.com.

Press Next at the top of your screen again.

Select the Google services (Mail, Calendar, and Contacts) you want to sync.

Unless you want to delete all the existing Contacts and Calendars on your phone, select the Keep on my iPhone (or iPad or iPod touch) option when prompted.
