IOS - Unlocking


Main article: SIM lock

Initially many wireless carriers did not allow iPhone owners to unlock an iPhone for use with other carriers. AT&T Mobility allows iPhone owners who have satisfied the requirements of their contract to unlock their iPhone. Instructions to unlock the device are available from Apple. This allows the use of an AT&T sourced iPhone on other GSM networks, such as T-Mobile and others. (However, because T-Mobile primarily uses a different band than AT&T for its 3G data signals, the iPhone will only work at 3G speeds on the T-Mobile 1900mhz network.) There are programs to break these restrictions.

Famous quotes containing the word unlocking:

    The mark of the man of the world is absence of pretension. He does not make a speech; he takes a low business-tone, avoids all brag, is nobody, dresses plainly, promises not at all, performs much, speaks in monosyllables, hugs his fact. He calls his employment by its lowest name, and so takes from evil tongues their sharpest weapon. His conversation clings to the weather and the news, yet he allows himself to be surprised into thought, and the unlocking of his learning and philosophy.
    Ralph Waldo Emerson (1803–1882)
