We require an app or small piece of software that can communicate with various models of smartphones and back up data to USB device. Looking for someone with experience with smartphones. The app can reside on our USB that plugs into phone OR it can be an app in the marketplace OR both. We would like the app to install and startup and ask user which files he wants backed up. Images, Contacts, Files, Folders etc. Simplicity is key. We want a bare bones version that works, then we will upgrade over time. Needs to be reliable as hell and easy as pie.
