Hi Dane.

I know nearly nothing about iPhone/iPod/iPad development, but i think this forum topic might be useful.

And if not. I suppose Apple has also released the iPad simulator along with iOS4 SDK, try debugging your app there.

Hope it helps.

Yeah, This is what I did to fix it. It wasn’t required before but for some reason now it is. I told apple about this in an error report about 3 weeks ago. But, thanks anyway.
