Specify iphone / iphone 4 programs

Any help on this would be much appreciated. I’m still finding my feet with corona, but I’ve got an app that I’d like to submit to apple. When I’m building for a device I can see the options to choose to build for either iPhone or iPad, so that’s straightforward.

My question is how do I specify either iPhone 3 or iPhone 4 from the build menu? Or will the program work on both? (I get all my screen sizes from display.contentWidth and display.contentHeight, so it all looks fine and dandy on the simulator).

If the program does work on the two, how do I get a hires default.png on the iphone 4 and a lower res default.png on the older iPhones? I don’t have access to an iPhone 4 to try it out unfortunately.

Or do I do two seperate builds, one with a low-res default.png, and one with a hi-res default.png?

Thanks for your help,

I guess I basically don’t understand what’s going to make an iPhone app different from an iPhone 4 app, other than it’s loading screen? In my case isn’t the code going to be identical? Or am I missing something?

I think I read elsewhere on these forums that one version won’t do for both iPhone and iPhone4? Any ideas? [import]uid: 9285 topic_id: 2693 reply_id: 7948[/import]

Silly me - always trawl the forums before posting : imageSuffix [import]uid: 9285 topic_id: 2693 reply_id: 7952[/import]
