As the iPhone 5 got into people’s hands last Friday, several Verizon Wireless subscribers noted that their iPhones were unlocked both for international use and for other U.S. carriers. James Duncan Davidson explains that Verizon isn’t doing this out of the kindness of its corporate heart, but rather due to an agreement with the FCC for licensing the 700 MHz C block of spectrum for its LTE network.

On 18 September 2012, Jeff Carlson is giving a free online presentation about the concepts and techniques in his book “The iPad for Photographers” at 5:00 PM Pacific (8:00 PM Eastern). Over the course of the hour, he’ll demonstrate how to import photos wirelessly from a camera to the iPad, rate and tag images while still on location, edit the photos directly on the iPad, and more. This will be a live demonstration (not just a set of Keynote slides), and there will be plenty of time for questions. Register at Peachpit’s site and tune in Tuesday!

Over at Macworld’s new TechHive site, Glenn Fleishman explains why LTE, the fast mobile broadband standard now available in the iPhone 5, is such a complicated beast, and why a “world” phone can work only across parts of the globe.

Over at Wired, a deaf iPhone user explains precisely why AT&T’s decision to take a core feature of iOS 6 — FaceTime video chat over cellular data networks — and make it available only to those with a shared-mobile plan specifically harms the deaf by forcing them to pay a higher rate with no associated benefit. The same argument is valid for all subscribers, but has particular resonance for those who use sign language.
