With Software and Soldering, a Non-AT&T iPhone-NY Times

George Hotz, 17, says he has unlocked two Apple iPhones and is using one with T-Mobile service.
AT&T is paying millions to be the exclusive United States provider of Apple’s much-hyped and glowingly reviewed gadget, the iPhone.
It took 17-year-old George Hotz two months of work to undermine AT&T’s investment.
Mr. Hotz, a resident of Glen Rock, N.J., published detailed instructions online this week that he says will let iPhone owners abandon AT&T’s service and use their phones on some competing cellular networks.
Mr. Hotz’s method, which requires a soldering gun, a steady hand and a set of obscure software tools, is one of several techniques that have emerged over the last week to break the technological locks confining the iPhone to AT&T’s network.
“This was about opening up the device for everyone,” Mr. Hotz said in an interview over his iPhone, which he was using on the network of T-Mobile, a rival to AT&T.
Carriers like Verizon, AT&T and Sprint seek to keep their customers in two ways. They force them to sign multiyear contracts, which are expensive to break. And the carriers put complex technological locks on phones to ensure that they run only on a given carrier’s wireless network. Without the locks, the phones could be used on rival networks that use the same underlying technology.
People who work on unlocking cellphones say those technical locks unfairly restrict customer choice. They want to give cellphone users the flexibility to take their phones with them overseas without incurring heavy roaming fees, or to transfer the devices to other networks once a user’s service contract has expired.
Mr. Hotz says it took him about 500 hours to unlock two iPhone units. He put one of them up for sale on eBay, and by late yesterday, bids on the phone had reached many thousands of dollars. An unmodified iPhone sells for $499 at an Apple store.
His technique is probably not accessible to most people. But Mr. Hotz described it in detail on his Web site in the hopes that others could simplify the procedure.
Neither Apple nor AT&T would comment on Mr. Hotz’s handiwork or on another unlocking technique revealed yesterday by an anonymous group calling itself iPhoneSimFree.
Members of that group demonstrated their technique to a writer for the Web site Engadget. They said they had developed a way to unlock iPhones with a software update, without any hardware changes to the device.
IPhone owners presumably would be able to run that software and then insert another carrier’s SIM card, the small card inside phones that run on G.S.M. networks. A SIM card stores information about the subscriber.
The writer for Engadget verified that the iPhoneSimFree technique worked. Apparently only one feature, AT&T’s visual voice mail system, which lets users retrieve voice mail in whatever order they choose, stopped working when an iPhone was removed from the AT&T system.
The six-man iPhoneSimFree group says that it has been working on unlocking the iPhone since June and that it plans to start selling its software to parties that want to unlock large numbers of iPhones.
The members have not disclosed what they intend to charge, and they declined to reveal their identities.
“We’re a bit paranoid about privacy because we don’t know how things are going to evolve,” said one group member, who identified himself only as Jim in a brief phone interview.
His caution stems from the murky legal status of unlocking cellphones.
Last fall, the Librarian of Congress issued an exemption to the Digital Millennium Copyright Act, ruling that people can legally unlock their cellphones. But the ruling does not specifically apply to people like Mr. Hotz and the iPhoneSimFree group who distribute the unlocking tools.
Apple and AT&T could conceivably sue such distributors under the copyright act. The companies could also argue that people sharing modifications to iPhones are interfering with a business relationship, between Apple and AT&T and the customers.
Apple might also seek to block the unlocking tools with its regular software updates to the iPhone. Mr. Hotz says he thinks his unlocking process is immune to such changes, because he is making a change to the device’s read-only memory, which cannot be changed with a software patch.
One other approach to unlocking the iPhone has made some waves recently.
Two weeks ago, a company called Bladox, based in the Czech Republic, began selling an $80 device called a Turbo SIM. The thumbnail-size card, attached to another carrier’s SIM card and inserted into an iPhone, tricks the iPhone into thinking it is running on the AT&T network even when it is not.
The company has reportedly been overwhelmed by orders and is not selling the product on its site. But Jesús Díaz, a technology writer in Madrid, said he bought the Turbo SIM last week and was now using his iPhone on Spain’s Vodafone network.
“Everyone here asks me: ‘What is that? Can I see it, can I touch it?’ ” said Mr. Díaz, whose iPhone draws a lot of attention because Apple has not yet announced a deal to sell the device in Europe.
The iPhone unlocking craze may have reverberations beyond Apple and AT&T.
Cellphone carriers in the United States generally subsidize the initial purchase of a phone and then work to keep customers paying the lucrative monthly fees. That is why operators offer incentives for loyalty and require long contracts.
But people now want the same freedom with their cellphones that they have with other devices, like televisions and computers.
Mike McGuire, an analyst at the research firm Gartner, says that even though few consumers will try these sophisticated alterations, the iPhone modifications point to “the rather rapid erosion of the carrier control of handset distribution.”
“This has been going on for a while,” he said, “and this is the latest salvo.”

Teen 'Unlocks' iPhone From AT&T Network -NY Times

NEW YORK (AP) -- Armed with a soldering iron and a large supply of energy drinks, a slight, curly haired teenager has developed a way to make the iPhone, arguably the gadget of the year, available to a much wider audience.
George Hotz of Glen Rock, N.J., spent his last summer before college figuring out how to ''unlock'' the iPhone, freeing it from being restricted to a single carrier, AT&T Inc.
The procedure, which the 17-year-old posted on his blog Thursday, raises the possibility of a cottage industry springing up to buy iPhones, unlocking them and then selling them to people who don't want AT&T service or can't get it, particularly overseas.
The phone, which combines an innovative touch-screen interface with the media-playing abilities of the iPod, is currently sold only in the U.S.
An AP reporter was able to verify that an iPhone Hotz brought to the AP's headquarters on Friday was unlocked. Hotz placed the reporter's T-Mobile SIM card, a small chip that identifies a phone to the network, in the iPhone. It then connected to T-Mobile's network and placed calls using the reporter's account.
T-Mobile is the only major U.S. carrier apart from AT&T that is compatible with the iPhone's cellular technology, but smaller carriers also use the technology, known as GSM. In Europe and Asia, GSM is the dominant network technology.
The hack is complicated and requires skill with both soldering and software, and missteps may result in the iPhone becoming useless, so few people will be able to follow the instructions.
''But that's the simplest I could make them,'' Hotz said.
Technology blog Engadget on Friday reported successfully unlocking an iPhone using a different method that required no tinkering with the hardware. The software was supplied by an anonymous group of hackers that apparently plans to charge for it.
AT&T spokesman Mark Siegel and Apple spokeswoman Jennifer Bowcock said their companies had no comment on Hotz' exploit. Hotz said the companies had not been in touch with him.
Apple shares rose $4.23, or 3.2 percent, to close at $135.30 on Friday. AT&T shares gained 26 cents, or 0.7 percent, to close at $40.36.
The iPhone has already been made to work on overseas networks using another method, which involves copying information from the SIM chip, or Subscriber Identity Module.
The SIM-chip method does not involve any soldering, but does require special equipment, and it doesn't unlock the phone -- each new SIM chip has to be reprogrammed for use on a particular iPhone.
Both hacks leave intact the iPhone's many functions, including a built-in camera and the ability to access Wi-Fi networks. The only thing that won't work is the ''visual voicemail'' feature, which lists voice messages as if they were incoming e-mail.
Since the details of both hacks are public, Apple may be able to modify the iPhone production line to make new phones invulnerable.
Analysts said it's unlikely Apple would overhaul the iPhone's wiring to thwart the new hack because the difficulty of the procedure is likely to keep it confined to hardcore hobbyists.
''I'm having a hard time figuring out where the real pain is going to come from in this,'' said David Chamberlain, principal analyst with market researcher In-Stat who follows mobile devices and services. ''Just selling the piece of hardware, they've made a nice profit off that.''
Apple has said it plans to introduce the phone in Europe this year, but it hasn't set a date or identified carriers.
There is apparently no U.S. law against unlocking cell phones. Last year, the Library of Congress specifically excluded cell-phone unlocking from coverage under the Digital Millennium Copyright Act. Among other things, the law has been used to prosecute people who modify game consoles to play a wider variety of games.
Hotz collaborated online with a large number of people to develop the unlocking process. Of smaller core group, two were in Russia.
''Then there are two guys who I think are somewhere U.S.-side,'' Hotz said. He knows them only by their online handles.
Hotz himself spent about 500 hours on the project since the iPhone went on sale. On Thursday, he put the unlocked iPhone up for sale on eBay, where the high bid was at $12,600 late Friday. The model, with 4 gigabytes of memory, sells for $499 new.
''Some of my friends think I wasted my summer but I think it was worth it,'' he told The Record of Bergen County, which reported Hotz's hack Friday.
Hotz heads for college on Saturday. He plans to major in neuroscience -- or ''hacking the brain'' as he puts it -- at the Rochester Institute of Technology.
