there is application ready deployment guide which also talks abt the activesync (EAS). There is no need for special VS. You just need to answer the ready application template (pg 12) which will greatly simplifies configuring the BIG-IP system for Microsoft Exchange 2010.
http://www.f5.com/pdf/deployment-guides/f5-exchange-2010-dg.pdf
You must be running BIG-IP version 10.2.1 or higher; version 10.2.2 or higher strongly recommended. If implementing Edge Gateway or APM in conjunction with your BIG-IP LTM deployment, version 10.2.2 is required.
There are two ways you can configure the BIG-IP system for the Outlook Web App, Outlook Anywhere, ActiveSync, and Autodiscover services:
- Separate IP addresses/virtual servers for each HTTP service
- One IP address/virtual server for all HTTP services
If you are using the BIG-IP Edge Gateway or BIG-IP APM for secure access to Client Access servers, you must use a single IP address. See page 28 for details.
I also understand there is mobile appl for IOS, Android (Samsung) but do note that BIG-IP Edge Client app does not support client-side checks. http://support.f5.com/kb/en-us/solutions/public/12000/400/sol12463.html?sr=17088698
