If my understanding of this: http://googleblog.blogspot.co.uk/201...-cleaning.html
Is that GMail won't have activesync, and so if you're one of those people like me who setup GMail on their ipad/iphone as an Exchange account (and in doing so got a calendar and contacts sync'd), will find it no longer be an option to setup after 30th Jan 2013.
Apologies if this has been reported elsewhere (a quick check showed nothing), or I misunderstood.
