Enable iPhone Tethering with Firmware 3.1.2
Posted on November 25, 2009 by eli courey
This is a step by step guide on how to enable the Internet tethering option (which Apple wants us to have but AT&T is blocking) on a jailbroken iPhone running firmware 3.1.2. Unlike other methods, this one will not break the visual voicemail feature. These steps were created from some posts on redmondpie.com.
Step 2: Move the downloaded CommCenter.patch file to your desktop.
Step 3: Make sure you have OpenSSH installed on your iPhone
- Open Cydia. Touch on “Search” tab and then search for “OpenSSH”.
- Install “OpenSSH” and reboot your iPhone.
Step 4: Connect your iPhone with your computer. Make sure iTunes is not running.
Step 5: Download and install Cyberduck for Mac. Enter the following details to login to your phone:
- Server: The IP address of your iPhone. Settings –> WiFi –> <Your Network Name>
- Username: root
- Password: alpine
- Protocol: SFTP (SSH Protocol)
Step 6: Navigate to /System/Library/PrivateFrameworks/CoreTelephony.framework/Support/and copy “CommCenter” file to your desktop.
Step 7: Start Terminal and type the following command:
- cd Desktop
- bspatch CommCenter CommCenter-hacked CommCenter.patch
A new file named “CommCenter-hacked” should now be created on your desktop.
Step 8: Rename this “CommCenter-hacked” file on your desktop to CommCenter.
Step 9: Now copy this new CommCenter file back to your iPhone in the following location using Cyberduck:
NOTE: Make a backup copy of the original CommCenter file on your iPhone so that you can restore to it in case something goes wrong.
Step 10: Now right-click on CommCenter file which you just copied, click on Info and change the permission to 755 as shown below.
Step 11: Restart your iPhone. Download and install the MobileConfig file by browsing to http://m.peacefulinsanity.com/Tether.mobileconfig from mobile Safari on your iPhone.
You should now have official Tethering option under Settings –> General –> Network.
Let me know if you have any questions or comments about this process. If you would like tethering on your 2G iPhone, I would suggest you install the MyWi app on Cydia.
