One XCode project, two target, two apps (iPhone/iPad) not universal app

Question

We have an XCode project that was first build as an universal app, and then on the road we changed our mind on having the two app in the same binary, so we created two targets.

1. The first one is called: AppName and is for iPhone: the base SDK is 4.2 and deployment target is 3.1.3. Targeted Device is iPhone.
2. The second is called: AppNameHD and is for iPad: the base SDK is 3.2 and targeted device is iPad.

It's been a few weeks now we are easily building for each of those platform and able to deploy on the both iPad and iPhone.

Now we are ready to submit to the app store and i'm worried about potential rejection of the code. We want to submit the iPad only app for now, but i've looked around there is nowhere in the itunesconnect site i can specify the targeted device, and as the project was structured first to be an universal app. I'm wondering how they determine on which device to test the binary.

More informations about the architecture: We are using the default generated info.plist file for both targets. Should we have a separate info.plist for each of the target? what differences should be present between the two .plist files.

Here is attached the actual info.plist file we are using.

Thanks for your help in advance.
