Forgive my probably silly question. I recently broke my Desire and bought a new one. I sold the broken one (all that's really wrong with it is that it won't detect any carriers.. I guess the antenna is busted or something) on eBay, and am about to ship it out. Suddenly the buyer emails me asking if it's unlocked, and if not, can I get him an unlock code. My carrier is Telus in Canada. I've since rooted and Froyo'd the broken phone. My question is, did installing the new software "unlock" the phone to be used on any carrier (assuming repair of the antenna)? Was it ever locked to begin with?
