Was working perfectly until as previously mentioned the damned market auto-updated the app.
Try to wipe and install again:
E/DeviceCapabilityManagerImpl( 6289): OperatorName=AT&T, Operator=310410, Product=htc_jewel, Model=htc_jewel not supported
Okay, change it to Galaxy Nexus, yakju and maguro per the SGS3 hack. Don't get the "not supported" any more, but perpetually stuck at "adding account".
Force stop, clear data, reboot several times. Repeat. Restore data only from TiBu (didn't work). Force stop, clear, reboot again. Finally, took a very long time, but appears to be installed again.
