I don't believe anywhere near 25% of iPhones in use in the U.S. are unlocked, but I'm sure a substantial number of them are in use outside the U.S.

Here in Mexico, people are going nuts for the iPhone. I've personally run across several people who are either using an unlocked iPhone on a Mexican system, or using a U.S. phone number (meaning, all-the-time roaming) so they can use iPhone.

This whole unlocking thing is my #1 annoyance with the iPhone phenomenon. As someone who has never jailbreaked his iPhone and has absolutely no desire or inclination to do so, it's annoying as hell to have to wade through all the jailbreaking "news" on the various web sites.
