BlackBerrys are indispensable to corporate employees because of their push e-mail capability. Now, that feature (using GMail) is also available on the Apple iPhone via GPush.

Google brags that without GPush, iPhone users normally have to wait around an hour before the e-mail will appear, this is not the case with GPush. The GPush Application retails for $0.99, gives iPhone users the ability to choose how they want to be notified of incoming e-mail:

GPush options include having the iPhone vibrate and ring and having the GPush icon display the number of unread messages received.

GPush will also let users see previews of incoming e-mails by displaying the sender’s name and subject heading.

GPush, the GMail push application for the Apple iPhone, can be downloaded via iTunes for $0.99.
