    I don't have a Pre, so I can't test this, but have been looking through the rom, and noticed a few things.

    #1 in the phoneprefs app in the javascript that control it, namely

    in app/controllers/preflist-assistant.jsjsjs

    there's a piece of code

    Code:
                    this.voiceRoamingChoices =  [
                             {label: this.carrierOnlyLabel,value: "homeonly"},
                             {label : $L("Automatic"),value: "any"}
                     ],
    I believe, this sets up a the drop down data structure that defines roaming settings.

    #2 if one looks at the binaries that control telephony

    or

    Code:
    spotter@dent:~/pre/resources/1/1/usr/bin$ grep homeonly *grep: ipkg: No such file or directory
    Binary file TelephonyInterfaceLayerCdma matches
    Binary file TilIpcTest matches
    grep: wx-config: No such file or directory
    one sees that it has a homeonly option that corresponds to what we saw above.

    a bit more digging.

    Code:
    spotter@dent:~/pre/resources/1/1/usr/bin$ strings TilIpcTest |grep homeonly
    211 : Set Roaming Mode (homeonly,roamonly,any)
    Enter Mode String: (homeonly,roamonly,any)
    and we see there is a roamonly option.

    so my guess is, if the above data structure is modified to have another element, namely something like

    Code:
                    this.voiceRoamingChoices =  [
                             {label: this.carrierOnlyLabel,value: "homeonly"},
                             {label : $L("Automatic"),value: "any"}
                             {label : $L("Roam Only"),value: "roamonly"}
                     ],
    one will be able to make it go into Roam Only mode.

    this is just a guess though, as I don't have a Pre to test it with, and I only advise you test this if you are comfortable modifying the built in pre applications as one has to do for some of the other hacks.
