iphone - Is the APN Device Token unique to each individual app?

Question

I have two apps on the iTunes store - both implement push notifications. While I was testing sending notifications to these production apps, I noticed that a push intended for app A was titled and opened app B.

Both of these apps are installed on the same phone. I looked in my device table and saw that the device Tokens (and of course, the Device ID) listed for the two apps were both the same.

As required, I am using two different certificates on the server - one for each app. I sort of assumed the device Token or certificate would route the message to the right app but clearly it isn't.

I can see in NSLog that the tokens being sent from each app are indeed the same.

Should the device Token be unique to each app? If so, any idea how my test phone could be sending the same device token for both apps to my server. Keep in mind this is from two apps currently on the app store.

Thanks for any help!

NOTE: this is an old answer that is true only for iOS <= 6. See user1641761's answer for the current approach.

Figured it out. The Device Tokens are NOT unique to the phone-app pairing. They are unique to the phone only. If you have multiple apps with push on the same phone they will all use the same Device Token. The certificate you use to send the notification will dictate which app it goes to.
