It's 2014. Nokia Lumia Black update. Lumia 1520 with GDR3 or whatever you call it. In March. STILL no VPN.
Thank God for 2X. Like Citrix except not annoying like Citrix or a PITA like Citrix and we replaced our entire Citrix farm at my company with an equivalent 2X farm, same number of servers, unlimited seats, a gateway app and the main host app plus got the printer issues from Citrix to go away and die for 1/3 the price it would have cost us to upgrade just our seat licenses to the new version of Citrix.
Mobile app works on all platforms and is free. Allows me to run thin client on workstations and tablets and run through HTML5, ASP, and gateway SSL on the phone and is lightning fast. Doesn't crash ever, and I can do anything on it that I can do on a workstation via virtual desktops that in most cases run full screen on the phone. Plus it has a mouse toggle built into the app and can also toggle the onscreen keyboard. Loves this app!
