IOS – How to find the iTunes Store link of an installed App

To get an app for free (if you didn't get the choice to pick None as payment option) you should open your installed ITunes program. Then from within the program go to ITunes Store and pick any free app and try to buy it (Google Translate or some other one). It will tell you to login/register into ITunes. If you create account from there you will have a choice to pick None as payment option.

This worked for me several times for my customers.

You can remove the country code from the URL, so it reads http://itunes.apple.com/artist/nash-the-slash/id160526527. That gives you a valid iTunes URL, that if opened in a browser (that doesn't auto-open iTunes), appears to be the same as if the link were a US link.

However when any iTunes link is opened in iTunes itself, it will attempt to redirect to the version in the user's local store. I.e. when I click on the link you posted, I get sent to the same item in the Canadian store.

If the item isn't available in the Canadian store, I get a message like this:

So, you should be safe using country-specific store links, and iTunes will handle the redirection as appropriate.
