Simpler workaround enables iPhone 3.0 tethering

updated 09:25 am EDT, Thu June 18, 2009

iPhone 3.0 tethering

A simpler method exists for enabling tethering with unsupported iPhone carriers, a new report claims. Although the iPhone 3.0 firmware provides the appropriate framework for the technology, many carriers continue to disallow tethering for fear of oversaturated networks. Hacks to enable the feature have typically involved a complicated series of steps that discourage adoption.

The new method involves only three steps, beginning with a line entered into Terminal in Mac OS X. Users then download a disk image intended for AT&T, or else one of a number of other carriers. After Option-clicking "Restore" in iTunes, users can then choose the alternate image, which activates the tethering option within an iPhone's network settings. Users should be cautious when enabling tethering, as carriers may penalize unauthorized data traffic.

    If the network is

    being overtaxed, then what is the point of using tethering? Won't that just slow down things more and possibly result in dropped calls for thousands of users in major cities. This is AT&T were talking about and they're probably already on the brink of network collapse.

    the network is not being overtaxed. Data is data- whether it comes from the iPhone or not. There will be a little more data via tethering, but not substantially more.

    If ATT wanted to prevent this, they should have had a plan set up. They new it was coming. s**** 'em.

    new =/= knew

    They "knew" it was coming.

    I agree with your sentiment. AT&T needs to be reasonable with respect to tethering.

    If AT&T can't handle

    The traffic, maybe they should get out of the way and let another carrier help them out by taking some of the iPhone users off their hands.

    Disables Visual Voicemail

    If you use that file you will no longer get voicemail notifications of any kind on AT&T. I had to restore.

    Not completely

    You just have to change Settings>General>Network>Cellular Data>APN to read acds.voicemail

    Works great! Weeeee

    one step

    Three steps, and Terminal?

    That's too complicated.

    I just downloaded a mobileconfiguration file from a handy website, directly to my phone, that includes a different APN setting, and boom. Works great in one step.
