Abstract: A modified computer program for a mobile device, tethered for use with a specific server, including tethering data (metadata tethered to the specific server; features or functions tethered to the specific server). Servers can provide databases, remote processing or storage, virtual machines, or specialized hardware or software that performs specific functions. A method for developers to submit mobile apps for review and tethering by agents, who examine descriptions of, and possibly try out, those mobile apps. Agents can determine whether to modify a mobile app to tether (or re-tether) it, and if so, can provide tethering data. The system either recognize elements in the untethered mobile app that can be modified, and modify them to tether it; or, the system provides software hooks for execution from within the mobile app. The system automatically submits the tethered mobile app to an app store. Tethered mobile apps are modified to both end-user login and login to the tethered server at once.
