They have nothing to do with each other. PRL stands for
Preferred Roaming List and only tells your device with towers to try first when in roam. You can update you PRL and if your not in/living in the affected area it wont do anything to your device. I run the newest Sprint PRL from
Here 60613. The 60711 I understand is a aircard PRL I have used in the past dont think it caused any issues. My ICS always works.
EDIT:
A old thread on the subject.
