Through Bluetooth forward calls and MMS from phone A to B. The phone can be Android or iPhone. These functions, like Bluetooth car hands-free device includes dial-in, dial-out, and send/receive SMS/MMS. And need to share phone B's contacts. This project must provide a complete source code and completed within a short period. If interested, I can provide the functional specification.
I do not know whether this feature can be achieved. If you have the ability to handle, place to bid.
