The Verizon iPhone 5 comes unlocked out of the box, a Verizon representative confirmed with CNET today.
A Verizon representative confirmed that it is "GSM unlocked" -- and that the iPhone is unlocked out of the box.
Of course, there are a bunch of caveats. This "feature" could be "fixed" via a future update. And AT&T's and Verizon's 3G/4G-class networks achieve different levels of connectivity speeds.
That said, iDownloadBlog, wrote on Friday that "the big news here is that we have confirmed that you can use a Verizon iPhone 5 on AT&T or T-Mobile, freely, even if you're a brand-new customer under contract."
