PhoneGap app (for apple) doesn't work

I am new to phonegap and coding so I am unaware as to how to use PhoneGap. First of all what I did was connect my PhoneGap (desktop) app thing to my iPhone PhoneGap developers app. On my iPhone it just says downloading... there is nothing else happening. I then tried using an Android phone to see if it works but it just says

unable to download archive from the server.
unable to properly connect to the server. 

I dont know what to do so any help will be appreciated.
