Google announced Tuesday the addition of Push notification for Gmail users on their iPhones, iPod touches, or Windows mobile devices through Google Sync. That means that users will no longer have to check for new messages on these devices, but rather that Google's servers will push them out directly, if the user so chooses.
"Using Google Sync," the company said in a blog post, "you can now get your Gmail messages pushed directly to your phone. Having an over-the-air, always-on connection means that your inbox is up to date, no matter where you are or what you're doing. Sync works with your phone's native e-mail application so there's no additional software needed."
Google also said that new configuration options will allow users to choose whether or not to sync Contacts, Calendar, or Gmail, or any combination of the three.
