An anonymous reader writes "It looks like Apple and its wireless operator partners have finally figured out a way of cracking down on iPhone unlockers by making it a requirement to sign up for a contract before you can get your hands one. "It's obvious why this has happened though. This method means you're tied into a contract, or you're paying O2 and Apple a massive wad of cash for the privilege of owning a 3G iPhone. We're disappointed about this decision, but it does make business sense." Both ATT in the US and O2 in the UK are implementing the new activation system on July 11th, when the iPhone 3G goes on sale."
