Check your current usage for any premium charges to see if it will be on your bill for this month. It should not show up if you unsubscribed last month like I did. Sprint will charge you even if you subscribe and unsubscribe in the same day. After you unsubscribe, sprint told me that the subscription expires at the end of your billing cycle and you have to resubscribe to it the following month if you want the channels again. You can always call Sprint to see if anything is on your account this month to make sure its gone.
Update
You can also unsubscribe using Sprint's website:
1. Log on to
http://www.sprint.com
2. Enter your username and password and click "Go".
3. Click on "My Content?.
4. Click on "Applications? at the top of the page.
5. Click on application.
6. Click on ?Unsubscribe?.
I am unsure if this works, but that was in an email from Sprint.
