Dev describes hack for AT&T iPhone 3.0 tethering

iPhone 3.0 tethering hack

Tethering an American iPhone should be as equally viable as tethering an Irish one, a developer tells MacNN. While AT&T has not officially opened up tethering in the US, local owners of an iPhone 3G and the iPhone 3.0 beta firmware should be able to hack their phones to use the technology. The process begins by navigating to the "~/Library/iTunes/iPhone Carrier Support" folder, where users must rename an IPCC file as a ZIP document after creating a backup of the original.

The ZIP file is then unpacked to a directory called Payload, where users must edit the info, version and carrier PLIST files. The first two files only require changing the CFBundleVersion variable to 5.0; the carrier file however requires adding a new dictionary to the apns array, with "apn = internet," "password = password" and "username = iphone" as variables. The wap dictionary demands a new pair, entered as "type-mask = (NUMBER) -2," and users may also want to enter a new pair in the top-level dictionary as "AllowEDGEEditing = (BOOLEAN) YES."

The Payload folder must once again be zipped up, and renamed to the title of the original IPCC file. At this point developers can sync an iPhone with iTunes and check for an update, which will allow them to pick their custom IPCC file. After a reboot, tethering should appear as an option in an iPhone's Network settings. Tethering is said to be non-functional for 2G (EDGE) iPhones.

    you could just jailbreak the thing and tether it. And you don't even need to waste your time with the v3.0 beta.

    This article has nothing to do with the Mac. I'm SICK AND TIRED of seeing all these stories about these dumb phones... you can't even hear people talking on them, they are static-prone as h***, they drop calls all the time. You can't even get reception on these phones inside the mall store that I work at! And there's an Apple store in this mall! THAT'S RIDICULOUS!

    I have a suggestion. Don't put any stories about anything other than Macs in It's like showing poker on ESPN2... IT'S NOT A SPORT!! The iPhone will earn my respect when it is offered for Sprint, which is the only carrier that gets reception inside the mall store that I am now sitting in. But even when that happens, report it on iPhoneNN or some other c***. I'm tired of all this c***!
