This is my take on the iPad ICCID disclosure — the short version is that (thanks to a bad decision by the US cell companies, not just AT&T) ICCIDs can be trivially converted to IMSIs, and the disclosure of IMSIs leads to some very severe consequences such as name and phone number disclosure, global tower-level tracking, and making live interception a whole lot easier. My recommendation? AT&T have 114,000 SIM cards to replace and some nasty architectural problems to fix.
