How to reset the device information in Google Play Store? I was using Samsung Galaxy with android, then I bought the new Motorola DROID RAZR using same SIM card.

when I'm trying to download any app from Google Play Store, it still refers to my previous device. How would I update my device information?
You can visit the accounts page in your computer and click on "Settings" tab. Under "My Devices" section you will have all the devices that your account is being tied with.
