Startup Idea : Carry a phone that Suits my Style

The idea is to create a service that lets people do the following: Virtualise their number (Multiple phones - Same Number) - User can decide which of the phone is active at a given time.- Sync up all my data based on preference across all the phones. For Eg: Work Data between Blackberry and Android while all my personal data, contacts between my Iphone and other android- Ensure if I install a game on the iphone, the same game is installed from Play on Android phone hooked to this service.- Remote Device management - Lost phone tracking etc.,- Federated Cloud storageThis way we can make sure a given user can / will carry more than one mobile with him/her which is a good thing for the industry.
