Google has announced that they finally added Push services to their Google Sync mobile product allowing you to always stay up to date and never lose contact information on your mobile phone.
I'm not a huge fan of checking email on a phone, but whatever works for some busy folks. I'm sure this product will be a huge hit for those who depend on Gmail for everything especially when they are on the go.
"Using Google Sync, 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 email application so there's no additional software needed. Only interested in syncing your Gmail, but not your Calendar? Google Sync allows you to sync just your Contacts, Calendar, or Gmail, or any combination of the three. "
