iPhone 3.1.2 OS kills tethering hack, iPhone Dev Team brings it back to life

If you’ve been using your jailbroken and modified iPhone 3G/3GS as a tethered 3G modem and you’ve updated to the latest iPhone 3.1.2 OS, you’re probably well aware that Apple (NSDQ: AAPL) has killed the iPhone tethering hack. Even if you updated to iPhone 3.1.2 OS through the Dev Team’s PwnageTool 3.1.4, iPhone tethering is a no-go. Fortunately, that’s something the iPhone Dev Team won’t stand for. EngadgetMobile has posted a tweet from Dev Team developer musclenerd which links to a workaround/patch that should allow advanced users (seriously, don’t mess around if you don’t know what you’re doing) to get iPhone tethering back in working order.
The advanced iPhone tethering workaround probably won’t do most users any good at the moment. It’s all very technical and involves changes to the baseband – something we’re too scared to touch ourselves. But, there’s still hope that the iPhone Dev Team can bake the workaround into future PwnageTool releases so that lay iPhone users like us can get iPhone tethering back online.
There’s also mention of a new workaround that will enable MMS on the original iPhone (iPhone 2G) – do with that as you will, but remember it’s at your own risk.

This really sucks man. Whenever I’m in the city at my wifi hotspot at Maccas, I tend to just connect via my netbook on my iphone but now with this, it looks like I’ll have to pay optus their tethering fee : /
Tried this on a 3G with 3.1.2. I got a tethered connection but could not get an IP address on my laptop. After a couple of attempts on both bluetooth and USB the tethering option disappeared again.
Solution? Downgrade back to 3.0 and then tether the sh*t out of your iphone.
Here are the instructions to DOWNGRADE your phone to 3.0 without touching the baseband…

I have done it in both, an iPhone 3G with 3.1 and on an iPhone 3GS with 3.1.2 and worked…
Only problem you can come across with is that VVM and MMS get disconnected. You can get everything working again following these instructions after you downgraded:

Good luck!
I dont CARE what’s the “latest code” apple has programmed for iPhone users, right now, I have not updated my iPhone for ages and I am happy with MY PRODUCT and I dont plan to update anytime soon specially because I am happy tethering on-the-go. So no thanks apple, I dont need your feature degrading update(s)!!
So people, just because apple releases its “latest piece of code/program/update” that doesn’t mean that you have to get it, its not obligatory.
Same I can say about my Windows PC, I am running Windows XP that hasn’t been updated since 2002, but I use third party firewalls and antivirus for which I do update, just not my Operating System. WHY? Because Microsoft released something called “Windows Genuine Advantage” which is a spyware tailored at spying at my activities, this was released as an “Update” so I dont need to “Update” to that. Same thing for my iPhone, I dont need to “Update” to not being able to use my iPhone as a modem, that’s not an update, that’s a DEGRADE!
