I don't see how an upgrade to Wi-Fi in the parks would correspond at all with having the ability to select extra FP's from smart phones. So while I think they will eventually make it available, it shouldn't have anything to do with wifi.
However this is the first I'm seeing of upgraded Wi-Fi in the parks and I think it's much needed. When using Wi-Fi in the parks sometimes it seems slow and rarely ever loads the
MDE app. So they've been needing to upgrade/update it for awhile now.
