Hi fellow developers, was after some information. Me and a friend are putting the final touches on an little game we created. We've went out of our way to make it support both iphone resolutions so people can use it on their new Retina display as well as 3GS/3G's resolution. I had a question about defining an app as HD. I've seen a new trend where people re-release their games with "HD" meaning it will support retina screen. Since our app will support both, whats the best way to do this. We don't want 3G/3GS owners to think their phones can't play the game cause certainly can. Does the App store have a way to let 3G/3GS owners know they can't download iPhone4 apps? thanks for any information you can provide.
