In the USA, AT&T has stated that the iPhone will never be unlocked.
Apparently the same is true elsewhere in the world.
Basically, Apple wants you to pay them $10-15 royalty a month for the rest of your life. Jobs must be laughing all the way to the bank.
Even if they've only sold two million phones so far, that's twenty million dollars a month they're taking in, supposedly to be used for software updates. I expect incredible software for that, not the wimp updates so far.
