I need to get imei on iPhones.
I use https://github.com/erica/uidevice-extension/blob/master/UIDevice-IOKitExtensions.m to get IMEI.
It works fine on iphone 4, 3GS ... even with ios5.
But with iPhone 4S, imei is empty. Does somebody have a solution ?
Thank you for your answer
Answer
If you have backup of that iPhone in iTunes, you need to go to Preferences >> Dvices, and the if you hover the backup you should see not only IMEI number but also Serial number and Mobile number.
You can check if that IMEI or Serial number are coreckt on this website: http://sndeep.info/en
Check when your iPhone was activated on this Apple web services: https://selfsolve.apple.com/agreementWarrantyDynamic.do
