How to Activate iPhone Tethering With Firmware 3.1.2 (3G and 3GS)

Now that Geohot has released the blackra1n RC3 jailbreaking tool, activating tethering on an iPhone 3G or 3GS is a snap. Many international users already have tethering, meaning they can share their iPhone data connection with a computer. AT&T does not offer this option in the US.

Fortunately it's never been simpler to tether if your iPhone is running the latest firmware (3.1.2). Follow these steps to activate tethering, just keep in mind you are breaking all kinds of agreements with AT&T and Apple in the process.

- First go to blackra1n.com to download and run the blackra1n RC3 jailbreak.

- After reboot, your iPhone is jailbroken. Find the blackra1n app installed on your iPhone and run the application.

- Touch “sn0w” and then the Install button in the upper right to install blacksn0w.

- Your iPhone is now unlocked. Open the web browser on your iPhone and go to the address: http://m.peacefulinsanity.com/Tether.mobileconfig

- Click install and confirm to update your IPCC file (carrier settings).

- Reboot your iPhone. Go to Settings -> General -> Network -> Internet Tethering -> ON.

- Now your computer or laptop can borrow your iPhone's data connection using USB or Bluetooth.

Worked super fast and easy..thanks!! (Will at&t charge extra for tethering?)

yes at&t will charge for tethering this year. Businesses already have access for $20 a month. A tech guy from at&t told me that they would charge around $30-$40 a month for non-business customers

Anyone noticed any problems with their WIFI not working all the time after performing this Tethering install? I do not know if it is coincidense or because of the tethering install I performed but now I am having difficulty getting my WIFI to find any wireless connections available ...in other words I turn WIFI on and normally I connect to my home WIFI and also see several of my neighbors .....but during the episodes when the WIFI is not working I do not see any wifi connections available nor and it does not see and connect to my home wifi. I did notice tonight that when the wifi on the phone was working I was only getting 2.5 mbps download using the speedtest app on the iphone via the wifi no matter which server I connected to...whereas before I was getting as much as 8mbps before the tethering install.

Please note that I am not sure if my WIFI issue is related to the tethering...I am simply asking if anyone else is experiencing what I am experiencing. Maybe my phone's WIFI is now defective and it will be time for me to restore firmware and take the phone to the store.

The same thing happened to my phone. I installed the config file on my phone, rebooted, and the tethering capabilities were available. Then I realized that my WIFI had also stopped working.

Have u figured out any fix for this yet?

My WiFi stopped working as well (3GS),
I have to uninstall the profile to get it to work, but that defeats the purpose..

How you was able to uninstall the profile to get Wifi to work again? I attempted to install internet tethering on my apple iphone 3g which has no service but a sim card inside. After I click install the screen went blank to the home screen from safari and now wifi do not work. Please help!

I jail broke long time ago. I just Applied config. Saw tethered. But all wireless networks are gone, including my home wireless. a) How to get back b) How to remove the config and restore old settings. Gave me heart aches.

Anyone know how to remove this tethering install? I remove the app and still show tethering available in the network settings.

I've completed the process and have the tether toggle setting. I have tethered in the past before upgrading to 3.1.2. My phone shows that i am tethering and my bluetooth shows that i am connected however i get no data transfer. i monitor my network in activity monitor and it shows some data received but no data sent. i have deleted the profile and reset my network settings and re-downloaded. i don't want to pay for mywi or even use airport to share. I want to tether the way it was intended via bluetooth or USB. Any suggestions?

has anyone noticed both 3G and wifi dropouts? I dont know if it is blacksn0w or the Tether.mobileconfig found at peacefulinsanity.com causing this but I need to find another solution for tethering(back to tinyproxy?)..
As I dont get the dataflows continuously in untethered mode its difficult to see without writing a script to see if I am getting the same dropouts sans tethered profile also.

Didn't work. It forced me to restore my iPhone settings.

Didn't work, it ended with forcing me to restore the settings.

It only partially worked for me. It enabled tethering, but disabled GPS and WiFi...and the purported fix ("reset network settings") almost bricked my phone. After about an hour of it being frozen with the "apple" logo on the load screen, I was able to re-sync it with itunes and restore...unfortunately it forced 3.1.3 on me at that point, so now I'm waiting for the new Tethering hack.

sorry to here that, i just did it right now and it works fine for me. did you reboot with rain or without it?

hold the phone, lol, now my wifi dosen't work but my gps does. well go figure.

I sync my phone as well and it forced 3.13.. How can get my tethering back on my phone?
Any ideas. ?

go to: settings/ general/ reset/ reset network settings
That should solve most of your problems with wifi after tethering. Mine works perfectly now.

For those of you with T-Mobile, if you go to:
settings/general/network/cellular data network
These are the settings I'm running with no problems (after I did the reset):

Iphone 4.0 3G with Itunes 9 unlimited data plan -----It was far more complicated then the I had hoped. I had freeze ups with downgrading to 3.2.1, I lost all my contacts (luckily I had an old sim) I had to solve a few problems with blackra1n errors and long load times, but If you want to kick Apple right in the pills for making us pay for what other phones could do for over 10years then it is well worth it. I paid 299.99 for this now obsolete phone and 100.00 a month for the plan when there are unlimited plans out there for 29.99. Downgrading to 3.1.2 also runs the Non 4g phones MUCH faster. What were you thinking Iphone?? This Miserable ordeal we loyal customers have to go through to compete with the Droid. Guess who's not sticking around for another two years?---This Guy!!

I tried the mytether app frombig boss and the bite my apple one and neither worked and I tried them 1000000 times. Definition of insanity. This worked for my on the first try I am amazed.

It seems that Apple has been on the phone SIM card in a trick used to strengthen the work of hooking the activation of wildcards used in the Sim card ICCID. This does not mean, however, was two days ago,
