If the PRL only better connects calls through the use of Sprints partners' towers, and its only purpose is to basically help with better reception in normally roaming areas, why are people hoping it fixes little issues with the phone (tests, missed calls, etc.)?

EDIT:
A PRL will not help with:

Improve signal strength in Sprint or roaming areas
Quality issues (Echo, Static, Cross Talk, Audio Weak, etc.)
Blocked Calls
Dropped Calls
Coverage holes (No Service is available to make or receive calls)
Fast busy signals
Providing added features to a Sprint PCS phone (such as voicemail)
Voicemail issues
Wireless Web issues
Receiving a Sprint PCS error messages on outbound calls
Correcting misrouted calls when roaming
Receiving a credit card prompt while roaming
