Why is it people need apps for GPush, I don't get it. I just got my mother an old iPhone 3G. She got her own maildomain, I hooked it up with the GMAIL servers and interface and enabled mail and calendar with IMAP. Then I set it up with the iPhone as described on the GMAIL help pages, and BOOM - exchange.. .pushes all her mails through GMAIL servers (also calendar). So... can anyone enlighten me?
