Yahoo uses push on the iphone?Push email without MobileMe
...
I don't see this happening based on what has already been announced.
If they want you to pay for push with MobileMe, why would they give it to you for free?
Yes, Apple will be providing the "push notification service" to app developers for free.
But from what I understand, you couldn't push email through this service.
It only supports text alerts [pop up message on iPhone], badges[numbers beside app icons], and sounds.
Now.. that said..
I imagine it is a possibility that Google could release a custom GMail app for the app store. They could provide the functionality of "pushing" sound alerts and badge updates for the app.
This way, it would seem like push email, same as the native mail app.. until you click on the GMail icon and open the app.
Now, you'll have to wait for the GMail app to download the email.
And if you read the posts you'll see that its up to Googs, not Apple.
The iphone supports IMAP and gmail uses IMAP. If Google begin using IMAP IDLE the iphone automatically becomes a push client.
Nuff said?
