iPhone new SDK (4.2) and plist on the device re-initialized

I've just updated XCode with the new SDK 4.2 and launched my app in my development environment, I see the app is asking me to register again: registration is a process I do once for the new users and I save the info in a plist.

Why it is asking me to do it again? I suppose for the new path of the plist or something.

Do the app's user see the same behavior? I hope not it would be a great problem to me!

I don't remember this behavior on the previous r开发者_开发百科eleases.

Any suggestion?

Thank you very much. Fabrizio

Is that plist file part of the XCode project? If it is, it was probably overwritten when you built the new version of the app onto your device. That is why you got the registration again.

Your users would have the same experience, I am guessing.
