Deploy iOS on specific devices only

Question

I was developing a game targeting iPhone 4 / iPad and higher .... My question is: can I somehow set the deployment goal so that it cannot work on 3GS or older devices?

All my textures for HD (iPhone 4 resolution), if it works on 3GS, all positions will be incorrect and all images will be oversized.

Are there any suggestions on how I can solve this problem?

Answer 1

Require front camera with SDK. 3GS will be excluded.
