Locally on the device this isn't possible. This is intentional on Apple's part - delete an app and you delete *everything* stored by that app.

This is also how users expect it to work by now, unless your app is a front-end for a web service such as a Twitter client, people expect a re-installed app to be 'new'.

Not sure this is possible, you might also need to read the iOS developer's documentation as I have a vague memory of access to that info being deprecated/not recommended/not being allowed to pass the information over the network.

Does your app require some kind of online password or account?
