IPhone iPhone appearance on iPad

So, I am working on a Cordova based app for both iOS and Android. The IOS part is designed to work on iPhone and iPod Touch only.

When I last submitted my app to view, I got this rejection message from it:

2.10: iPhone Apps should also work on iPad unchanged, at iPhone resolution and 2X iPhone 3GS resolution

The thing is, my app looks like on iPad:

I was hunting for another app that also works on iPhone sized iPads, and I found FourSquare:

As far as I can tell, they work at the same resolution.

I made a call to $ (window) .width () and .height () in my application and I get 320x480, which as far as I can tell is the resolution of the original iPhone.

I found another SO question here that addresses a similar (I think) problem: 2.10 iPhone apps should also run on iPad unchanged, on iPhone resolution and on 2X iPhone 3GS resolution

But when I check my settings ([project target]> Application Icons and Launcher Images), Launch Image Source is set to LaunchImage and Launch Screen File is empty. (my experience with native iOS and storyboard settings is limited, so I'm not sure if I am following the solution given in the linked SO question correctly).

I also found the following here: Make an iPhone app specific iPad app to meet Apple requirements

He talks about modifying one .plist file to remove all links on iPad. I found two entries in my "CFBundleIcons ~ ipad" and "Base nib file name (iPad)", both of which have no values ​​(the value column is empty). Should I delete them? I'd launch them to try, but I'm a little scared that I could blow something up without repair (plus the time it took to try, submit and wait for Apple to come back to me is infinity + 5 seconds, and the project is already behind schedule, as it is :().
