You cannot use wifi on your gopro. The only phantom that can use wifi is the vision. Personally I would go with the phantom 2 and zenmuse and buy the hero3. Multiple reasons. You can use the gopro outside of the phantom (i.e. Snorkeling) but the camera on the vision is stuck on the vision. You'll also notice that right now everyone is talking about wanting to buy a gimbal for their vision. When you factor in the cost of the vision then the cost of a gimbal for it, you would have spent much more than you would on a P2. You also will get better video with the gopro. I look at it like this, the vision is like an iPad, it's idiot proof and made so that everyone can use it out of the box. The P2 is like an Alienware gaming computer. You can do a lot more with it and really tweak it nicely but you're every day old man isn't going to understand how to use it.
