I am using the below code in my application which works perfectly in iPhoneOS 3.1.3 but not working in iOS 4.0. Any body affected by using this.
NSString *c
It appears that the SBFormattedPhoneNumber key/value data has been removed from the NSUserDefaults object as of 4.0. No device number retrieval love; can't really say that the writing wasn't on the wall based upon Dylan's response to this thread.
