iOS Publishing Device Settings and iAds

chad.allen

I have an app that will have a free (with ads) and a paid for version (no ads).
It will be available on many devices.
My main concern is with iOS. Do I need to create on iTunesConnect a new free app
for iPhone legacy, iPhone Retina, iPad, and then a paid version app for each device as well?
I modified a version in GameSalad for each device because if I publish say from iPad version
then online after its there I publish to iPhone it doesn't look right (cutting screen off or showing too
much). I have tried using Resolution Independence and tried without it. Doesn't seem to change anything.
So, after my testing, I'm figuring I need a GameSalad file for each device and double that for
a version with ads and one without. Is that correct?
I figured its easy enough on Amazon cause its only the Kindle and on Google Play it automatically
changes for each device.
So my main question is with iOS, how do I upload several device versions to an app on iTunesConnect
or do I have to make several apps on there just saying, App Name iPad, App Name iPhone, App Name Legacy iPhone,
App Name iPad Free... etc...

I can't seem to figure this out or find an answer about this somewhere.
I guess I don't understand how this works.

If I could get some help soon that would be very nice since I am trying to release this next week.
