The wallpaper and icons issue you guys are seeing is a very, very old bug in PPST and nothing new at all. It does no damage, and is really not reason to be any more careful than you would have been otherwise. These updates are generally applied by a stock rom RUU on your running device *before* flashing the new ROM, therefore, they are followed by a hard reset. You are running the update manually and alone and may see the PPST bug.

No offense to anyone, but if you are not willing to hard reset your device you probably should not be here looking for PRI updates to apply manually.

Also I can't guess what PRI stands for but what it is is non-volatile settings. For example, if you go into PPST and change your audio codec from EVRC to Voice 13K, that setting will remain after a hard-reset or ROM flash, because it is an NV (non-volatile) radio parameter. These are what the PRI sets. A new PRI means a change in some parameter passed to your radio at low level.

It is my guess that Sprint has not made a change in an existing variable, but instead the new radio probably looks for new parameters that needed to be set by a new PRI.
