Submission + - Push Gmail for iPhone and Windows Mobile (blogspot.com) 1
Selikoff writes: "Google has expanded service to now include push Gmail for iPhone and Windows Mobile, previously only supporting limited Exchange services such as Calendar. It seems Google didn't work directly with Apple on this subject, instead choosing to leverage the existing Exchange protocol previously available within the iPhone. From the article "Google rolled out an upgrade to Google Sync which now provides the ability for Gmail messages to be pushed to mobile devices rather than pulled. That means that e-mail messages sent to Gmail accounts will be received immediately on mobile devices rather than having to be summoned at 15 or 30 minute intervals by the device.""
