Renamed Google Apps User and Sync. How to reconfigure? Since renaming his Google apps account, one of my employees Droid Razr can't sync. I'm sure it's still pointing to the old user name. He is running 4.0.4 on his Razr. 

Can he reconfigure his device without wiping it? if so, how?
Is it a primary google account? - if it is, a factory reset would be needed, meaning a wipe unfortunately...
