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.

“Nae living man I’ll love again,
Since that my lovely knight is slain.

I’ll chain my heart for evermair.”
