Hi guys,

So my team and I are developing an app on iphone and ipad but we don't know everything in dev yet, so I'm not sure about what elements I have to give to my developer. Any answer will be awesome :)

Do we (designers) have to make two different mockups for an iphone app because of the size of iphone 3 vs 4 retina? or the iphone 4 mockup is enough because the size rescale automatically when the developer code it?

And what about the normal view and the large view, you know when you flip your iphone, how does this work on the developper side? What elements should I give to my developer?

(Sorry for my english, I'm doing my best :)
