With V3 I can build now and it will send the compiled code to either my iPad or my iPhone, and it works great!

But, what aspect ratio should I be designing my game for in the editor? Right now I’m using iPad Wide (4:3). Will that work for iPad, iPhone 2/3, and iPhone 4?

If it won’t work for iPhone 4, do you suggest doing different releases for the 4 platform?

The aspect ratio is not the same for all the iDevices (iPhone is 4:3, iPhones are 3:2). This shouldn’t affect the scene display too much, but you will need to design the GUI so it looks right with both aspect ratios. There’s some code in this thread that shows a simple way to scale GUI elements to suit the screen.
