Xcode 3.2.2 and iOS 4.0

Here is a little tip for the developers.
If you have updated your iphone to iOS4 and you want to continue to develop your application for iPhoneOS 3.... you will have the "good" surprise.... you can't test it on a device with iOS 4.

Here is a solution :
* Install XCode 3.2.3 with iOS4 SDK.
* Copy the folders :
/Developer/Plateforms/iPhoneOS.platform/DeviceSupport/4.0 (8A293)
* Install XCode 3.2.2
* and move your backup folders at the same place...

Just it works ^^... you can compile your applications for the SDK 3.0 and test it on the SDK 4.0.
