Explanation: For firmware 3.1+. Carriers which are officaly known to the iPhone database will show your carrier logo, otherwise it will try to show your carrier name instead. This package is only useful if you do not see currently ANYTHING in the top-left corner of SpringBoard. If you don't see an logo / see a wrong one, please install a Carrier Bundle for your operator (and don't ask me where to get one).
