What is the proper setup for Gmail on iOS
I have been struggling with this since I made the switch to iPhone in November. I use gmail and would like my emails to be sent from my own domain. Exchange no longer works. Any help is appreciated
iPhone 5
Google stopped supporting their version of Exchange (ActiveSync) unless you have a premium GMail account.
The "proper" setup depends on your preferences and needs.
You can use the standard iOS profile to set up your GMail account using the standard iOS Mail app, or use the GMail app. The GMail app supports Push, the standard iOS GMail does not.
If you want your Google contacts to be available on your iPhone, the GMail app will pull a contact into a new message without the contacts actually being installed in your iOS Contacts app, but of course they won't be available for any other purpose. The standard iOS profile for GMail does not let you sync your Google contacts, so the best route is to set up your Google contacts as a CardDAV account:

This is done as an additional account to your iOS GMail account (or just set up contacts only and use the GMail app).
The GMail app does not provide Calendar or Notes support, only the iOS GMail profile does.
Personally I use the standard iOS GMail account for Mail, Calendar, and Notes, and set up a separate CardDAV account to sync my Google contacts. I'm OK with not having Push support for mail, there are more important things to fret over.
