Since about Friday, I have not been able to purchase apps or even update currently installed apps in Google Play Store. I get an error code of 921. Have deleted cache and data from Google Play Store as well as Google Framework then rebooted and this has not helped.

When I am online at my desktop and go to Google Play Store and have it list my devices my old Sprint Galaxy Nexus shows up and not my current AT&T Galaxy Nexus. I did sometime last week boot up my old Nexus to get the Ice Cream Sandwich update but it has no service with Sprint. I thought it could be used as a music and gaming device.

Does anyone know how to get back to having my current phone listed?
