Today Alltel announced that they're going to be offering simple push email to their Windows Mobile customers in the form of an app they're calling “Alltel Mobile E-mail.” We call it “Seven” and know and love it in its free Beta Program form. The Beta offers their latest and greatest and it's one of my first-installs on any mobile device.
If you're not down with the Beta, though, Alltel will ship their email app (which integrates with Outlook Mobile) on new devices and should offer a download to existing customers as well (link to that pending). The release brings Alltel up to speed with the other big US wireless carriers in offering a version of Seven's push email client on Windows Mobile, each branded with the carrier's respective identity.
So we're curious because it's a perennial question: Have you found a solution to get push email for your email that isn't Exchange? What is it?
