Hey guys, there is a thread over at XDA on updating your PRI to 1.4 if you are stuck on 1.34. Ignore all the garbage about needing Unrevoked Forever, you don't. Here are the steps that seem to be working.
Type in ##786# into the dialer, hit menu and chose reset and punch in your MSL. Your phone will clear out all data and settings except for your SD card. It will then reboot and do hands free activation, check for a PRL and firmware update. Somewhere in there you should get a newer PRI.
You can check your PRI version in About Phone under Software Information. If you don't succeed at first, keep trying...and trying...and trying.
Restoring your nandroid backup will not overwrite the new PRI, so you can get your phone back to the just the way you like it.
I'm not sure if there is a difference or just a placebo. Web pages seem to load faster. Some pre and post speed tests might have been helpful but I didn't have the foresight to do that.
Edit:
You may be able do the same thing without wiping your phone. Not sure if the wiping is a necessary part or what yet.
Steps:
Dial ##3282#
Enter Edit Mode
Enter your MSL
Select Data Profile
Menu
Restore
Let Phone Reboot, and Wait and the Hands Free Activation will Start.
Repeat until you have 1.40 PRI.

To do a complete wipe, you will need your MSL code. Call sprint and they can give it to you.Originally Posted by rjmjr69
DO NOT USE ANY FILES
New directions
1. BACK UP YOUR PHONE USING WHATEVER METHOD NANDOID ETC
2. Get your MSL code either thru Sprint or using CDMA
3. ##786# wipe your phone
4. Reboot phone
5. Repeat steps 3-4 if it does not work the first 15 times!!!
Good luck
This tested and proven on TWO phones in my possession and by a few others here already posted
