iPhone Tethering Changes Locked in 3.1?

In a comment on iPhonewzealand.co.nz, a user has pointed out that changes to tethering have been locked out in iPhone firmware 3.1. I imgaine this is at the behest of the big carriers like AT&T, in order to stop people making changes to their tethering APN to get around plan limits.

The unfortunate side effect is that it prevents users in New Zealand from modifying tethering to work on the XT network. iPhone calling and browsing still works, but tethering is currently broken.

There is a suggestion that small changes to the profile (ipcc) file will fix the issue. Check back for updates.

  1. I am a iPhone app developer and I am running 3.1 and I can change apn’s just fine

  2. Please note I have had heaps of emails form people based in USA. Sorry I can’t help you apple has blocked the hole that allowed that. I am in new Zealand where we don’t have that restriction put on us .

  3. Can you please send some info on tethering for iPhone OS 3.1…when the 3.1.1 comes out will tethering be something standard? In any case, in some small countries (like Bulgaria) the mobile carrier do not change their ipcc file that much…or do not have that many differences…anyway, appreciate all info.

  4. Hi Jon,

    I am from Macao (China) and owe an official unlocked iphone 3GS.
    So happy to find your post, can you please help to tell how to reactivate the tethering. Desperate want it back without downgrade or jailbreak it.
    Big thanks.
