Heads Up! iPhone 3.1 Beta 2 Disables Tethering!

Posted on 15 Jul 2009 by Josh Gard

After I posted the update to the Internet Tethering process last night, I came across a post on MacRumors where it’s being reported that the iPhone OS 3.1 Beta 2 has disabled the Internet Tethering capability for US AT&T customers. I have not yet personally verified this as I’ve not loaded the 3.1 beta on my iPhone, but due to the amount of comments on MacRumor’s site from people who’ve discovered this, I felt it at least warranted a warning. If you’ve updated to OS 3.1 beta 2, and have noticed this, let us know in the comments!

  1. Indeed, the tethering has been disabled. I'm very disappointed by this, as I've been using the tethering feature on AT&T almost daily. I am happy to report however, that Pandora has been fixed! As have several other bugs in the beta 1 release of 3.1

      Thanks for the comment Jared. I'm disappointed by this as well, since I use the tethering quite frequently, though not daily, but several times a week. I have a feeling this is going to keep a lot of people on 3.0 until AT&T officially enables tethering later this summer (as they announced at WWDC).

    I use the tethering daily. I don;t care what fancy new things are in the 3.1 update, I'm not upgrading until it's fixed.

  3. Could the whole "hack your iPhone with a text message" thing been a trick/ lie to get people to update to 3.1?

      I really doubt that – for a few reasons. The lead researched who discovered the vulnerability is very well-known and respected in this area. The vulnerability has also been shown to affect other mobile platforms, including Android and Windows Mobile. And the Black Hat conference that it was unveiled at is full of the world's top security experts from all sides of the fence. Nearly every year, there are some fakes and plants and so forth – and they are just about always outed very quickly by the veteran hackers that attend. I've heard nobody doubt the credibility of this vulnerability.

      No, that was to get people to update to 3.0.1, in which tethering still works.

  4. Well it broke my tethering, and I want it back!!

  5. Mike says:

    To clarify, 3.0.1 fixes the SMS vulnerability. 3.1 is a new OS update presently in closed beta. Big difference. 3.0.1 still allows tethering at present.

  6. Shake says:

    3.1 definitely disables tethering. Wish I could go back to 3.0.1 firmware.

  7. Tom says:

    Yes, foolish me updated before realizing this. I too would rather go back to 3.0.1 to get tethering to work.

  8. Brad says:

    Thank god I waited to update until I searched online to see if tethering would be disabled.

    I have no plans to upgrade to 3.1 until tethering is an option with AT&T.

    And if AT&T charges for it, not a problem….I'll just cancel my AT&T wifi at home (AT&T: You will NOT swindle me!)

  9. Joe says:

    Does anyone know how to go back to 3.0.1?

  10. Richman says:

    There is no chance to go back to fw 3.01 or 3.0. From this day on apple is dead for me and i will change my office from 7 imacs back to win machines :( thx guys!

  11. spidermonkey says:

    Yes there is a way to go back but you will have to jailbreak

    • UppityWomyn says:

      warning about Jailbreaking, Apple will not support jailbroken phones. Hot on the heels of the release of iPhone OS 3.1 comes word that the House of Jobs will no longer support firmware restores of versions 3.0 or 3.0.1. So if your jailbroken 3GS goes south on you, you're up the creek sans paddle. ~from ismashphone.com
