I'm trying to prompt the user (once, I record it) to upgrade the iphone app if it is out of date. I've found a few sites that explain how to get the link to your app in the app store once it is already there. Here's one for example (http://bit.ly/6QIC40).
The problem is, all these guides require the app to be in the store before you can get the ID to link to it. This is a new app. Is it impossible to figure out what your app ID (and link) will be before submitting your code? Therefor it is impossible for your first version to have an upgrade link embedded?
