The boffins at Google has just added Gmail support to Google Sync for iPhone, iPod touch and Windows Mobile-powered devices, where you are now able to receive Gmail messages as they arrive as long as you maintain an over-the-air, always-on connection. No more excuse for not reading and replying your emails, eh? We would highly recommend you get an unlimited data plan if you want to take advantage of the latest Google Sync, otherwise you might get hit by insane data charges if you download and view the many attachments your friends send over. Just a little sidenote – Google Sync enables one to synchronize just your Contacts, Calendar, or Gmail, or any combination of the three.
