Google announced today that they are discontinuing Active Sync services on their gmail service. This is a very geeky way of saying that Push notification on Mail applications on the iPhone and Windows phones will not longer work making gmail useless on those devices.
While this can be described as diabolical on the part of google, for iPhone users its not all bad news. Google offer a gmail app for the iPhone that will continuing to work in something like a useful fashion so if you really wan to use gmail on your iPhone you still can.
But there is no such application for the Windows Phone and Google have, and I quote, “no plans to change that”
