Ok it was a very long wait for those of us who bought the wifi back pack to see our GoPro video on our iphone (and other devices too)
But it's out today.
I've tested it and there is like a 3-4 seconds delay so no live streaming that could help us to do cheap (near) FPV... but it's nice to make sure your landing gear/arm is not in the shot. Also you can see if your lens is clean...
It's pretty much it... kind of a bit sad there is such a long delay... maybe some firmware update will make it faster later..
Update your cineform software to latest before up update the wifi pack and gopro hero2 firmware.
It was a bit bumpy installation (firmware upgrade) but worked in the end.
Let me know if you get better lag time...
