Bunny, I guess I wasn't clear. This isn't really a forum to discuss the details of Apple devices, so I'll make it brief. When I said they have different versions, what I meant was that the two OS's, (iPhone and iPad) are not the same OS. You can't run iPhone OS on iPad, and vice versa. The most obvious indication of this is when you go to the app store and find some apps will run on one, but not on the other. "Whats App" is a perfect example of this. Because the two OS's are different, you can have problems with third party applications (the
Tello App) on one, and not the other. I'm not sure if you saw the continuation of the thread, but after updating my iPhone OS, the issues I was seeing went away. I now use my iPhone to crash my
Tello into walls, lamps, and miss doorways by a few inches.
