Many people’s biggest disappointment with iPhone 3.0 is there’s still no push Gmail. (Probably due some to contractual snafu of some kind.) According to TechCrunch, that is about to change (maybe). I say maybe because the software to do this, named GPush, has not been approved by Apple as of yet.

GPush is a 99-cent app that almost fixes it by sending you push notifications whenever you get a new message.

It’s very simple: you enter your Gmail account information and that’s it. On the backend, it’s actually using Gmail’s standard IMAP idle function (but on the developer Tiverias‘ servers), so there’s a slight delay between the mail hitting your inbox and the notification getting pushed from them to your phone. But the 10-30 seconds lag reported is totally acceptable, especially since you get a pop-up preview of the email.

Two things: it isn’t made clear if it supports more than one Gmail account, and all those pop-ups could get annoying, if you get a ton of email, anyway.

Oh, and it’s possible Apple won’t let it into the App Store. They say none of their code violates Apple or Google’s ToS, but as many point out, we all know how “reasonable” the App Store review process is.

Update GPush is now available from the app store
