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.

“They learned to rattle the lock and key
To give whatever might chance to be,
Warning and time to be off in flight:”
