Microsoft Auto / Ford Sync Modification

I am looking for a modification / patch for my Ford Sync system. It is for a 2010 Ford Escape XLT in case this is important. I have two phones paired with my Sync system, however I am disappointed in the Sync's limitations and wish to have someone here modify my software or code an addon that will allow for this to happen. **The scenario:** 2 paired phones. Phone A is set as the primary phone and phone B is paired and always present as well. **The problem:** Ford Sync will only use the phone A as it is the primary phone. **The solution/job: **Make Ford Sync use both phones simultaneously. For outbound calls ONLY use Phone A (because it is primary phone). For incoming calls, broadcast all incoming calls through vehicle's speaker system regardless of what phone they are coming in on, and regardless of which phone is set to Primary in the Sync software settings. (As long as no conversation is taking place already, of course.) If the Sync system is already broadcasting a call, then ignore the call and let the phone ring as it normally would. **The pay: **You will be paid the amount of money you request in your bid for this job. If your product is coded in such a way that it can be marketted to other Ford Sync users, then I will be offering a 35% royalty on every copy sold. You may provide an online activation system that decrypts the software after activated / paid for to ensure that you receive your royalties if you wish. Any other form of protection is also acceptable, but of course not required and at your discretion.
