4g ipod slowdown

Hey there.
we have been developing a game for the 3g and have just tested it for the first time on the 4g.

2 immediate things (problems ) show up.

  1. the frame rate has dropped dramatically instead of improving as we had predicted.
  2. It seems that some of our button hit areas have moved.

has anyone had this problem?
thanks,
Chris

We have corrected our problem.
It seems that the native resolution option threw our game into hd resolution settings that we hadn’t anticipated.
It is fixed fro now by choosing standard resolution for both 3 and 4g versions.

thanks thanks
