Display the name of sip provider and for cellular calls displays the
carrier logo.

From Bruce:
"Maybe a more intuitive solution would have been to load the GSM button
with
the current carrier logo being used in the status bar. This way if a
user was to
spot ( AT&T, VODAPHONE, T-MOBILE ) instead of ( GSM ) in the blue
button,
there would be no confusion what it was used for."

The ( CarrierName ) Key is here. Judging by the width of the STATUS
BAR it's probably a print of ("%4s")

[ Example 1 ]

iPhone $  plutil -v StatusBarImages "/private/var/mobile/Library/
Preferences/com.apple.carrier.plist"

       {
       AllowPrefixMatching = 0;
       CarrierName = "at&t";
       DefaultImage = "Default_CARRIER_ATT.png";
       FullScreenOpaqueImage = "FSO_CARRIER_ATT.png";
   },
       {
       AllowPrefixMatching = 0;
       CarrierName = cingular;
       DefaultImage = "Default_CARRIER_CINGULAR.png";
       FullScreenOpaqueImage = "FSO_CARRIER_CINGULAR.png";
   }
)

[ Example 2 ]

iPhone $  plutil -v StatusBarImages -v CarrierName "/private/var/
mobile/Library/Preferences/com.apple.carrier.plist"
