SIM lock
(redirected from iPhone unlock)

    Also found in: Wikipedia 0.01 sec.
SIM lock
(Subscriber Identity Module lock) A function in GSM cellphones that restricts the phone's use to a particular cellular carrier (a particular SIM card). SIM locks are used to ensure subscribers finish their service contracts when the phones are heavily subsidized by the carrier. SIM locked phones may be unlocked by entering a code.

Apple's iPhone brought the SIM lock into public view because of its exclusivity with AT&T in the U.S. However, iPhones have been readily "unlocked" by hackers both in and outside the U.S., not only to use a different carrier, but to customize their appearance and download applications even before Apple debuted its App Store. In addition, Apple sells the iPhone without the SIM lock in Australia, Taiwan, Hong Kong and other regions, where locked phones are either prohibited or are a recipe for marketing failure. See SIM card, jailbreak and iPhone.

The makers of the iPhone unlock claim it is upgrade and restore resistant- meaning updates from Apple will not interfere with the design of the hack, or interfere with it in anyway.
