Anti-theft measures in Apple's newest mobile OS will cause huge problems for legitimate resellers.

iOS7 Poses a Problem for iPhone Resellers One of the new features of iOS 7, Apple's newest mobile operating system that's poised to drop in the fall, is "Activation Lock," a security implement designed to stop i-device thieves by making the phone so that it cannot be wiped clean (via the erase all content and settings option) or restored to a new device without knowing the password of the previous iCloud account that was associated with it. Many people sell their iPhones. Either they're upgrading, have damage and choose to unload it to someone who'll fix it, or they swap platforms or carriers. Many people are also technical novices. They forget passwords; they don't understand how cloud storage systems work, etc. Unfortunately, these two realities are going to cause lots of trouble with the new "Activation Lock" feature. Yes, it will stop thieves, but Activation Lock security is also going to screw honest people buying second-hand phones from other honest folks (and definitely honest people buying phones from not-so-honest folks). The iCloud password of the account associated with the phone is now going to be necessary to activate or even wipe the phone. Its tied somehow to the UDID, and so it can't be bypassed. No restore or DFU mode will get you out of this quagmire. Its going to end up with strangers whom you sold your phone calling and asking for your password, or some pissed off consumers ready to draw and quarter you because they think you tried to get over on them.
