I KNOW SOME U GUYS AND GIRLS KNOW THIS BUT SOME PEOPLE DONT
SO I WAS SREACHING THRU FORUMS AND I FOUND THIS GUIDE TUTU IT WORK 100% FOR ME CUZ IM IN SUNCOM HERE IN PUERTO RICO SO THIS IS WANT U HAVE TO DO
This works in 1.1.4 too! Here is a guide. Its basically yours, I just tweaked it abit.
1. You must have a 1.1.3 or 1.1.4 Jailbroken iPhone with SSH and BSD Subsystems.
2. Navigate to /System/Library/Carrier Bundles/Unknown.Bundle
3. Copy the carrier.plist to your desktop and create a copy of it
4. Convert the plist file here so you can edit it.
5. Search for: <key>AllowPrefixMatching</key> <false/> (there should be more
then one... Just take the first one.)
6. Replace <false/> with <true/>
7. Right under AllowPrefixMatching, there should be a <key>CarrierName</key>. This carrier, for me, is Vodafone. It might be different for you. You can actually edit any carrier name, be it AT&T, O2 or T-Mobile. Just make sure you set AllowPrefixMatching to True.
8. Replace Vodafone (or whichever carrier you picked) with your carrier. Note that this is case-sensitive.
9. Replace the Default and FSO.png of the carrier you change. So, if you changed Vodafone, you got to replace the Default and FSO Vodafone png.
10. For the logo that appears in the springboard, it is the FSO.png. For the logo that appears in applications, its the default.png. Once you replace the images, restart your iPhone.
HERES IS A MUCH EASIER WAY IN MY CASE I DONT NEED VODAFONE CUZ IN
PR DOESNT WORK SO I JUST EDITED THA CARRIER.PLIST LOOKING FOR vodafone and (Default_CARRIER_VODAFONE) AND (FSO_CARRIER_VODAFONE) AND CHANGED WHAT EVER SAYS ABOUT VODAFONE TO MY CARRIER THAT IS SUNCOM AND THEN I LOOK EN THE Unknown.Bundle AND CHANGE DEFAULT AND FSO VODAFONE.PNG TO MY CARRIER THEN I RESTARTED MY IPHONE AND IT WORK
AND TO EDIT THE PLIST GO TO THIS URL
http://140.124.181.188/%7Ekhchung/cgi-bin/plutil.cgi
AND THEN JUST OPEN NOTEPAD A DROP THE CONVERTED PLIST IN THERE WHEN DONE EXIT NOTEPAD AND SAVE
SUNCOM SCREEN SHOT
MODDED SCREEN SHOT
JUST IN CASE U GET LOST LOOK FOR THIS IN THAT CONVERTED CARRIER.PLIST
<string>vodafone</string>
<key>DefaultImage</key>
<string>Default_CARRIER_VODAFONE.png</string>
<key>FullScreenOpaqueImage</key>
<string>FSO_CARRIER_VODAFONE.png</string>
THEN CHANGE IT TO WHAT EVER CARRIER U HAVE THATS NOT TMOBILE AT&T VODAFONE ECT..
LIKE FOR EXAMPLE MY CARRIER IS SUNCOM I DID THIS
<string>suncom</string>
<key>DefaultImage</key>
<string>Default_CARRIER_SUNCOM.png</string>
<key>FullScreenOpaqueImage</key>
<string>FSO_CARRIER_SUNCOM.png</string>
SAVE AND THEN PUT IT IN THE Unknown.Bundle WITH THE MODDED CARRIER.PLIST
RESTARTED AND THEN U HAVE UR MODDED CARRIER
HOPE U UNDERSTAND THIS TUTU
