iOS 5-没有更多的UDID-即使删除了应用程序，如何保留一些关键数据来识别用户

Question

I've just read on a blog that the UDID will not survive iOS 5. I use it as an identifier combined to an app ID I generate myself. Without that UDID, I will just have the App Identifier but as it is stored in the userDefaukts for the moment, it is deleted if the app is uninstalled.

How may I do to keep it safe even if the app is deleted from the iPhone ? I have to achieve this to ensure that I have at least one stable identifier, even if it's not the sole one I use to identify the user.
