    Time to upgrade your PRL (Preferred Roaming List) for your iPhone! The PRL is what ViPs (and all Verizon phones use) to choose the systems to connect to. It can enhance battery life and connectivity, especially while traveling.

    To update, dial *228 and choose option 2.

    To check your PRL, dial *#5005*4357#

    I'm up to 52257 woot!!

    Got it - didn't see the change in version number until power-cycling.

    Just tried updating mine. It didn't change after programming. It stayed at 52219.
    Interesting.

    Did you reboot the phone? As in power off, then back on? Mine appeared to not update until power cycling.

    If your phone does not reset the signal, power off the device and restart and you should have the new PRL.

    You are on Verizon, right?

    If so - you need to call in and have tech support look things over - those 3**** PRLs are for non-smart phones. Smartphone PRLs are 5**** and 6****

    30266 here also. Was 30265 prior to update. I wonder if it is due to the fact that I am on an old Alltel plan?

    That explains it. But actually, even in the Alltel plans, the smartphone PRLs were 4**** - it still may be worth calling to tech support.

    I updated mine this morning. Thanks for the heads up.

    Interesting side note ... I seem to remember other phones automatically rebooting to load the new version. I wonder why the iPhone doesn't do this.

    Thanks for the heads up. Now up to date with the rest of you hear. The few speed tests I have done since the update show significant improvement in my 3G speeds. Also, didn't need to reboot here.

    The PRL in the phone is Preferred Roaming List - it's a database of system IDs the phone uses to know which towers to use and where - in a preferred order. So - when you are in an area where your carrier does not offer native service, it defines for the phone what towers it's able to use. And in some circumstances, the PRL can allow "in market roaming" where even in your home area, your phone might prefer another company's tower even where native service is available. Roaming agreements between companies can change fairly regularly - thus updates are required - doing the process to update regularly isn't a bad idea... certainly a good idea to do before leaving home on an extended trip/vacation. I'll update about every 6 weeks or so - or, when I see a discussion like this, and find my PRL is outdated.
