Yes, but that's a daas yachid.  The mainstream view is that they had the 
formula but it was only to be used in emergencies.  They used it in 
Bavel, but stopped when they returned, and resumed in the mid-4th 
century CE.  According to that view there's no reason to suppose the 
formula was not the same one we have, with the possible exception of the 
"Lo ADU Rosh" dechiya.

Zev Sero            Wishing everyone health, wealth, and
