iOS Testing apps on previous IOS version?

[cthesky]

Hi all,

I am testing my application on IPhone / IPad device with IOS 5.0.1. But I need to make sure the application also running well in version 4.3.3. So is it possible to restore my IPhone / IPad devices to IOS 4.3.3? Or if the application running well in IOS 5.0.1 means that it also can running well in IOS 4.3.3? Am I required restore my devices to IOS 4.3.3? The restoration only available for jailbreak devices?

Any ideas and comments are welcome and appreciated. Thanks a lot.

Download previous versions on Mac OSX for your simulator?
Then you can test it on there, I know it's not the best solution but..
You can allways pickup some old iPod touches, which run the iOS you want to test on it.
