Change Carriers for Iphone to Custom Logos or Text!!

This has been tested on IOS 4.3.2 on 3gs working Perfectly with Vodafone India.
Now to change it follow the procedure :

• Go to /System/Library/Carrier Bundles/Your_Carrier.bundle
• Replace both the FSO_CARRIER_Your_Carrier.png and the Default_CARRIER_Your_Carrier.png files with the images you want (image can’t be any higher that 20 pixels).
• The same thing applies for any other carrier, just select the correct .bundle for you carrier.

Have Fun!!
