Hi developers around the world, the app I am making is for in house distribution, we used some Apple's little secrets to get the app working as we want: like getting the IMEI and IMSI with methods described here: get IMEI on iPhone with CoreTelephony?
It worked fine for last 2 years, but since more and more people in the company moved to iOS 7, we found this method no longer suits our need - it simply returns a nil in iOS 7. The whole system is designed to hold IMEI and IMSI info, modifying it would require a considerable amount of effort, so we would rather focus on getting the IMEI and IMSI info out of the device.
My research has lead me to this article: https://code.google.com/p/iphone-wireless/source/browse/wiki/CoreTelephonyFunctions.wiki , which described a private method called __CTGetIMEI. However, I don't know how to use this method since it looks like a C level method. If so one could point me to an example, please help.
