iPhone 3.0′s Broken Push Messaging Caused by Unlocked Phones
Earlier this week some iPhone 3.0 users started receiving random instant messages seemingly intended for other people. It was later uncovered that this was caused by unlocked iPhone users.
The iPhone generates unique public/private keys upon activation that identify handsets to secure those pushed IMs, and unlocking tools use duplicated keys to facilitate illicit use. With single identifiers registered to multiple phones instant messages are being sent all over the network – rather than to their intended destination.
