I just ordered a phantom 2 vision and have been reading about the lag with FPV on the iPhone app. I'm trying to piece together what my best course of action will be to have good experience when it arrives tomorrow. Since I have no older versions of the iPhone app because I just downloaded it for the first time and since I'm assuming it will not come with the newer version of the firmware on the phantom does anyone know if the FPV lag is present if I keep an old version on the phantom and have the new app for the phone? Hopefully that makes sense. Thanks for your help.
