For anyone that is curious about this here is a brief description. By doing this my reception improved.
(Preferred Roaming List)
The PRL is a list of information that resides in the memory of a digital phone. It lists the frequency bands the phone can use in various parts of the country. (The smaller bands within Cellular or PCS, technically called blocks.)
The part of the list for each area is ordered by the bands the phone should try to use first. Therefore it's a kind of priority list for which towers the phone should use.
For example, say you had a Sprint PCS phone, and were travelling in an area with no Sprint coverage, weak Verizon coverage, and strong Qwest coverage. The PRL would tell the phone to look for towers using Sprint's band for that area. Finding none, it might tell the phone to search for towers in Verizon's band next, perhaps because Sprint's roaming agreement with Qwest was not as favorable, or none existed. The phone would use Verizon's towers, as dictated by the PRL, even though Qwest might provide a better signal.
Since a PRL tells the phone "where" to search for a signal, as carrier networks change over time, an updated PRL may be required for a phone to "see" all of the coverage that it should.
Since upgrading to 5.0, I've not been able to update my PRL with Sprint. I keep getting the following error: "Your preferred network list could not be updated. Please try again later. If the problem persists, contact your wireless service provider". Any help would be appreciated.

did you click on the Network Connections icon and hit the Options button and click on Update PRL? that is how I did it after upgrading last week. Also, are you upgraded to Sprint's official OS 5? I had some problems updating PRL when I was on the leak 5.0.0.419
For sure, let us know how it goes. Apparently some users were able to hop on Verizon EV easily, and others had to force 3G mode. Hope it works for you.

the users i was referring to had non-blackberry devices, and had an option to force 3G bands. i think some berrys have that option, but definitely not all.

No current BB on Sprint has the ability to force roaming. The only current Sprint phone that can force roaming is the Palm 755p
