That's a tall order. The Bionic doesn't actually have a carrier lock. Verizon uses a different type of network than most carriers (CDMA instead of GSM). It is possible to change the settings, but it involves connecting your phone to a Windows computer via USB, rooting it, and changing some RadioComm settings. Bricking is a strong possibility. I would recommend simply buying a new phone, perhaps an unlocked Nexus. If you're still interested, the necessary steps are scattered around several forums.. (I should probably make a complete guide sometime, but I'm kind of lazy.)
