I built and ran an iOS 4.3 app in Simulator. It initially brings up an iPhone 4 shell. Although all real iPhone 4s have retina display, this simulated iPhone 4 only has a resolution of 320x480.

I look in Hardware > Device. There's a checkmark next to the normal iPhone. So I'm using an iPhone 4 case but displaying normal iPhone resolution? I'm already confused!
- iPad
- ✔ iPhone
- iPhone (Retina)
I then switch over to iPhone (Retina). Strangely, it opens iPad with the same 320x480 resolution. Both the shell and the resolution are wrong here!

How am I supposed to turn Retina on and off and show it in the right shell?
