You can't run any process when your application is not actually running - this includes at download time and at uninstallation.

Instead, you should try to find other ways to measure what you want. You can, for example, have your application keep track (in NSUserDefaults or similar) of whether or not this is the first time the user has launched your app, and if it is submit the UDID to your server.

Tracking uninstallation is a lot harder - the best you may be able to do is to keep track of how long it's been since the user last launched your app (if you have the app submit a launch time every time the user opens it).

Keep in mind that a lot of tech-savvy users will object to your gathering the UDID or usage patterns within your app without their express permission (or at all).
