John,
The encryption algorithm, one of several which protect the GSM air interface is in the sim card. It is my understanding that a backup algorithm, also in the sim card, can be switched into use at very short notice by the network operators.

In the longer term, a completely new algorithm can be introduced by replacing the sim cards.

The scientists working on the project used an old computer with a huge hard drive to crack the code. The system is not secure, its been broken. Future sim cards can be broken much more quickly now that the project has a model. As scientists we deal in discoveries and the reported discovery is GSM is not secure. CDMA has a natural encription that defies attempts to crack it. CDMA was developed during WWII as a secure radio link. Qualcomm doesn't hold the patent on CDMA, just the commercial implimentation of it. Terrorism is the reason the scientists have been working on this, they have been using it for some time.
