How to get IMEI on iPhone 5

Question

I'm develop application for jailbroken iOS devices. I use https://github.com/erica/uidevice-extension/blob/master/UIDevice-IOKitExtensions.m to get IMEI, but on iPhone 5 this solution does not work(return empty string). Is there any way to get IMEI on iPhone 5(iOS 6.1.2)?

Answer 1

There are several ways to get IMEI on newer devices

1) Private ManagedConfiguration.framework

CFStringRef MCCTIMEI()

2) CoreTelephony.framework

struct CTResult
{
    int flag;
    int a;
};
extern CFStringRef kCTMobileEquipmentInfoIMEI;

void *connection = _CTServerConnectionCreate(kCFAllocatorDefault, NULL, NULL);

NSDictionary *info = nil;
struct CTResult result;
_CTServerConnectionCopyMobileEquipmentInfo(&result, connection, &info);
[info autorelease];    
CFRelease(connection);

NSString* IMEI = (NSString*)info[(NSString*)kCTMobileEquipmentInfoIMEI];

3) liblockdown.dylib

extern CFStringRef kLockdownIMEIKey;

void* connection = lockdown_connect();
NSString* IMEI = [(NSString*)lockdown_copy_value(connection, NULL, kLockdownIMEIKey) autorelease];
lockdown_disconnect(connection);

I had some problems with MCCTIMEI - returned empty IMEI after device start-up. Now I'm using CoreTelephony solution, never had a problem with it.

UPDATE

On iOS 7 these APIs are protected by com.apple.coretelephony.Identity.get entitlement. To access IMEI (IMSI, phone number and other info) you need to sign your with that entitlement with boolean value set to true.
