SIM Lock
Most network-supplied versions of the Universal are shipped SIM-locked, with the O2 XDA Exec being a notable exception. There is a free SIM unlocking tool released by buzz_lightyear on http://www.buzzdev.net/. This process involves flashing a new Radio ROM onto the device, and may invalidate the warranty.

Famous quotes containing the word lock:
“There warn’t anybody at the church, except maybe a hog or two, for there warn’t any lock on the door, and hogs likes a puncheon floor in summertime because it’s cool. If you notice, most folks don’t go to church only when they’ve got to; but a hog is different.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
