As you may not know when you go to activate your new P4, just like a new P3, you will need to be connected to the internet and you will need to choose a name for your P4. Walk through the wizard slowly as some have made the mistake in the past breezing through the setup and in the end getting a name they did not intend, like "Inspire 1". The name you choose cannot be changed, ever. So think about the reprocussions if you choose something like "MonkeyBalls1". You might have a problem when you go to sell it later on down the road. You can contact DJi and whine and moan all you want, many have in the past, they will not let you change the name even if you bought it from someone else used. I suggest the simplest and cleanest name, "Phantom 4". Choose wisely....... **** Also, I would also wait for the official iOS and Android versions of the App before trying to connect to the P4. I have already read an Apple Store buyer here in these forums state that he used one or the other current versions of the GO App to connect to his P4 tonight and it named his P4 "Inspire 1". Not good but I guess "MonkeyBalls1" would have been worse.
