The tiny SIM cards (Subscriber Identity Module cards) that most mobile phones are equipped with when they are purchased from a wireless carrier pack a lot of pertinent data about the phone and its user, such as contacts, text messages and geo-location information. The mobile phone manufacturer syncs the phone and the SIM card so the phone can only be activated with the SIM card provided by the manufacturer for that particular device, and the SIM card can only be used for that particular device. (It is non-transferable to other phones.)
Though the iPhone's manufacturer (Apple) goes to great lengths to ensure the popular iPhone will be inoperable without a SIM card, it is possible (through third-party software) to crack open the iPhone's software and force a recovery of the original factory settings without the SIM card lock (a process often referred to as "jailbreaking" a phone). Best of all, jailbreaking an iPhone is now completely legal.
