If you're already a paying HMA customer then you get the new iOS app free of charge, but if not then all you need to do is sign up for your Hide My Ass VPN account day, which you can get for as little as $7 per month - almost as cheap as Netflix!
So if you're sick of seeing "This content is not available in your country" on your iPhone or iPad you need to get yourself the HMA app for your iOS device today - it's very easy to download and install and gives you access to over 450 servers in 60 different countries.
Any other advantages? It's a hell of a lot faster than other VPN services out there, or trying to struggle through using a proxy instead. If you want to unblock streaming websites/other foreign websites then you'll need the Hide My Ass app for iOS - no two ways about it.
