Can iOS receive gmail's instant (within several seconds) push notification for email?

I want the ability to send an email to an iOS users iPad's POP account and have them instantly recieve a notification.

For example, on my Android devices, since gmail is built into the system, if anyone emails my gmail address, I get a notification about 1 second after they hit send on their end. If its a pop account, then I have to wait until the next pull, every 15, 30, etc minutes (whatever the user has it set to).

Can iOS receive the gmail type instant notifications? And if so, how does the email account or notifications settings need to be set up?

Solution 1:

You cannot have Push notifications for a POP3 email account. The only supported mail accounts for push email notifications are iCloud/MobileMe and Exchange with ActiveSync support.

Solution 2:

On the iPhone if you go to Settings > Mail, Contacts, Calendars > Fetch New Data you should see the option to turn Push on. It's not always perfect and not all protocols support it so there's another section below it called Fetch. When Push can't work Fetch will retrieve data at the intervals you set which are Every 15 minutes, Every 30 minutes, Hourly, or Manually (meaning only when you open the email client and/or tell the client to sync).
