What is PRI on Device Information page?

[xzr1tv]

I just had to replace my TP with a new/remanufactured unit. On the "Device Information" page, all of the values from "ROM Version" thru "Current Username" matched EXCEPT for "PRI Version"....

Old phone had a version like "2.03_......"
New phone has a PRI version of "1.47_003".

A) Should I be concerned?
B) What does this value control? What effect between the different versions?
C) When I talked to support @ Sprint store, they stated it could be updated, but if requires a HARD RESET.

Any help is appreciated.

Unless I was doing it wrong, I searched these forums, and also tried various GOOGLE searches but could not get a definitive answer.

its probably your radio version. just a wild guess, but thats the only thing on my DI page with an R haha, aside from ROM date.
