OpenVPN Android Application

We need the application to be able to connect via OpenVPN using UDP/TCP. We will provide examples of what we'd like the end product to look like. Features/functionality we're looking for include: App should list a Recommended/Favorites/All category for the server selection. Servers will be grouped into Continent>Country>City. Server trees should be able to take domains or IPs without issue and be expandable to facilitate more or less servers at any given time. Integrated trial offer. App should allow a user to download and start the trial with only an email and prevent use after the 7 day trial period. Prompts user where to upgrade to a full account. Protocol should be user select-able from a settings menu. UDP would be the default with TCP as an option within the application.
