Dev:CoreTelephony.framework

CoreTelephony is a public framework that manages telephony related tasks on iOS. It can be used as a frontend to communicate with CommCenter which talks to the baseband directly. The public portion is only a tiny part of the whole framework.

CTSettingCopyMyPhoneNumber
On iOS 7 returns null.

CTSettingCopyMyPhoneNumberExtended
On iOS 7 returns: { kCTSettingMyPhoneNumberEditable = 0; kCTSettingMyPhoneNumberExists = 0; } No error is output to the console and I tried every entitlement that MobileSMS has, however there still might be a different entitlement required.
