That way, I can open up xCode is each version I have. The only downside is that each folder you create is about 5-6GB's. But if you have a large HD, you should be fine.

I would recommend changing your Base SDK to 4.0 and setting the target to the desired platform. Sid, 3.2 is only available for the iPad.

Hi John,

Following your instructions I’m getting a ‘Warning’ message when testing my app on my device.

How to rectify this problem.

I noticed that I get this feature for 4 - but only if I set the deployment OS to 4.0. Is there no way to get this behavior for iOS 4 while not losing 3.1.x compatibility? Thanks Hi,
