4200 Series

I. I have a 4201S, can this also be upgraded to GPRS?

Yes, you can also upgrade a 4201S to GPRS functionality. Before being able to upgrade this, you must first upgrade the 4201S to a 4202S. The reason for this is that the 4202S is the �data-centric� test set and GPRS is a data service.
