Sprint has completed rollout of PRL 60654, and it has begun being pushed to devices.
The PRL release quickly (in PRL terms) followed the release of 60653, and applies to all modern EV-DO-enabled phones. It is not known at this time what, exactly, the update has made changes or improvements to.
To update your phone manually, select the PRL Update option from your Phone/Tools/Settings menu. If your phone does not have that option, call *2 and request to be flagged for the update.
