Can I change the carrier name in the iPhone Simulator 5.0? I found numerous instructions to set SBFakeCarrier in com.apple.springboard plist but this doesn't seem to work with iOS Simulator 5.0. 

Is there any way to change the carrier name in the simulator?
For my part, I was able to change the carrier name for the iPhone 5.1 simulator by editing this file:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/System/Library/CoreServices/SpringBoard.app/French.lproj/SpringBoard.strings


As the path suggests, I'm French. Switch to whichever localization you choose.

Inside this strings file (editable with XCode if it's a binary plist), you'll find a SIMULATOR_CARRIER_STRING key. Change its value, fire up your simulator, and there you go.
