PRL updates (the 20xxx series) are general, across-the-board updates for EvDO devices.
I do dispute some of the assertion made about PRLs, namely "increased signal strength" and "better battery life".
The former is not possible for non-roaming purposes as cell phones automatically pick up new Sprint towers without the need for PRLs (preferred roaming lists). So that is just non-sense.
Same with better battery life unless you "roam" a lot since you'll have new towers available.
Having said that, PRL 20224 doesn't add much, in fact THIS is what it does:
Quote:
Network Acquisition
No network acquisition changes.
Domestic Roaming Coverage
Changes were made to the PRL to assist customers with the Treo 700p. The Treo device was unable to receive voicemail indicator and place and receive calls while roaming in Norfolk, Virginia. The issue was confined to Treo devices.
Additionally, a change in carrier preference was made to Digital 800 CDMA roaming systems in central Wisconsin.
Customers who live or travel with tri-mode and digital dual mode devices or EVDO devices can obtain a PRL update to take advantage of this change.
