Teen hacker untethers iPhone from AT&T network
Advertisement

NEW YORK -- A teenager in New Jersey has broken the lock that ties Apple's iPhone to AT&T's wireless network, freeing the most hyped cell phone ever for use on the networks of other carriers, including overseas ones.

George Hotz, 17, confirmed Friday that he had unlocked an iPhone and was using it on T-Mobile's network, the only major U.S. carrier apart from AT&T that is compatible with the iPhone's cellular technology.

While the possibility of switching from AT&T to T-Mobile may not be a major development for U.S. consumers, it opens up the iPhone for use on the networks of overseas carriers.

``That's the big thing,'' said Hotz, in a phone interview from his home in Glen Rock.

The phone, which combines an innovative touch-screen interface with the media-playing abilities of the iPod, is sold only in the U.S.

Calls to AT&T and Apple for comment were not immediately returned.

The hack, which Hotz posted Thursday to his blog, is complicated and requires skill with both soldering and software. It takes about two hours to perform. Since the details are public, it seems likely that a small industry may spring up to buy U.S. iPhones, unlock them and send them overseas.

``That's exactly, like, what I don't want,'' Hotz said. ``I don't want people making money off this.''

He said he wished he could make the instructions simpler, so users could modify the phones themselves.

``But that's the simplest I could make them,'' Hotz said.

The modification leaves the iPhone's many functions, including a built-in camera and the ability to access Wi-Fi networks, intact. The only thing that won't work is the ``visual voicemail'' feature, which shows voice messages as if they were incoming e-mail.

Hotz collaborated online with four other people, two of them in Russia, to develop the unlocking process.

``Then there are two guys who I think are somewhere U.S.-side,'' Hotz said. He knows them only by their online handles.

" I would assume this kid is smart enough to check the legal side of things before openly stating to the media 'Look what I did.' If I was one of his parents, I'd be proud of him. He did this and only broke one, sort of useless in my opinion, part to the phone's software. Kudos to him and the others around the world that helped him. I'd also like to add: PWNT! "

" It's hard to argue that Apple is trying "to corner a market" or "limit free trade" considering there are probably a billion active cell phones out there in and they've just got started. The phone only works on AT&T's network because AT&T was willing to work with Apple on getting the product to market. The visual voicemail is one such example - AT&T had to ignore their existing voicemail system and build this from scratch to work with the iPhone. Shouldn't AT&T and Apple be allowed to reap the rewards for their innovation, at least for a little while? "

" Actually, there's a specific exemption in the DMCA regarding unlocking cell phones. So, apparently, he's in the clear! "

" Not withstanding the countless number of copyright and FCC laws this kid has probably broken in doing this, I'm sure that somehow the Dept. of Defense will deem it a matter of national security and throw him in jail under the Patriot Act. "

" Good for him. I think their sould be a federal lawsuit since this lock is a way of limiting free trade. Sounds like Apple is trying to corner the market by making a device that only can be used on a certain network. Waits for the feds to sue Apple as they did with Microsoft. "

" This is actually a pretty remarkable technical feat, especially for someone 17 years old. The iPhone's a very complicated device with a lot of proprietary parts. It's not really unlocking something that the phone could do anyway - it's making the phone do things it doesn't even have the right hardware to do. My main worry is that he's opening himself up to DMCA violations. It's a crazy bit of legislation. "

" I am sure his parents - who paid an ungodly amount of money for that phone really apreciated him taking it apart and soldering things together on it!! I don't really understand what the big deal is...Apple PUT a lock on it to specifically block this type of usage - sooo OBVIOUSLY there would be a way to UNLOCK it.???? All he did was figure it out... "
