    I tried this : *5005*86*123456789#

    "123456789" is replaced with number of my choice. I have youmail account and is connected to my phone number right now. Every time I call my voice mail from phone app it says that I have no voicemail( I do but it's on the youmail account) the default number is useless to me right now.

    Also the youmail number to access my voicemail is 10-digit. But the method I found above is only limited to 9digits. I tried putting 10 digit in and press the call button, the screen flicker every time I press call.

    Is there anyway I can go into the system file w/o jb to change the default number to the 10 digit youmail number?

    Btw, i have factory unlocked 3GS on tmobile.
    Thanks!! :)

    get TetherMe(paid app) from Cydia then edit your carrier.plist, it's found in:

    /System/Library/Carrier Bundles/iPhone/Your Carrier.bundle

    Info: Appl£ signs the carriers now so you have to use TetherMe $4.99 to get past the signing process

    (there could be some other tweak that stops the signing process)

    Edit: look for this in the Carrier.plist:

    <key>VoicemailPilotNumber</key>
    <string>Your number goes here</string>

    Mine looks like this:

    <key>VoicemailPilotNumber</key>
    <string>443</string>

    Edit 2: if your carrier.plist doesn't have it try adding it,

    make a backup copy before editing your Carrier.plist
