With internet tethering enabled you can use iPhone internet connection on you desktop or notebook. Here is a quick tutorial for experienced users. For everybody else – just wait for the new version of PwnageTool or some other utility.

Here it is:

A bsdiff patch to apply to CommCenter in 3.1.2 to re-enable tethering is available here for the 3GS and here for the 3G. It’s just a 2-byte patch as shown below (and an appropriate readjusting of the mach-o’s codesign hash):

USE THIS AT YOUR OWN RISK! Your carrier may end up charging you for unauthorized tethering access.

Update #1 It looks like a lot of people have been looking at CommCenter lately because IRC user CleanAir had a similar tethering patch. Meanwhile over in the 2G CommCenter, WhiteRat and geniusan have patched in native MMS support for that platform. Kudos to CleanAir, WhiteRat, and geniusan for digging into CommCenter and coming up with patches!

Update #2 A few tutorials have started to pop up. Eventually this will be made a part of the normal PwnageTool flow but for now this is best left for the adventurous users out there!

bsdiff patches are the normal way that PwnageTool modifies Apple software. To apply one manually, you must first get the “bspatch” program. Then do:
bspatch CommCenter CommCenter-hacked CommCenter.patch
If you don’t have bsdiff but know how to use a hex editor, the differences are available here in text format.

The correct SHA1 of the hacked file will be:
1b19712035f33654cf72838ebe1a2033931b56b2 # 3GS
063165c3fa3e21d30eb4b486fab924ba3ef0ea5e # 3G
You would then remove the original program and replace it. Don’t forget to ensure it has execute permission!
chmod +x /System/Library/PrivateFrameworks/CoreTelephony.framework/Support/CommCenter
After you’ve started using the hacked CommCenter, visit http://www.benm.at/help/help.php from your iPhone and install a new mobileconfig.

DevTeam says that 2.2 update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future. Use new version of PwnageTool (not avaliable yet, but will be soon).

Some fact:

• The 2.2 firmware for 3G contains a baseband update for the 3G iPhone
• The 2.2 firmware for 2G (1st gen iPhones) doesn’t contain a baseband update and the baseband is still at 04.05.04
• Pwnage technique (and therefore the Jailbreak) isn’t affected, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT install 2.2 using iTunes as you will lose your jailbreak

• If you apply this update and you previously relied on PwnageTool or QuickPwn to activate your phone, it may become temporarily deactivated and unusable (until we release the new version of PwnageTool or QuickPwn).
• PwnageTool and QuickPwn updates will be released as soon as possible that will allow a safe update path to 2.2 the release of these updates is inevitable but not imminent, we are creating the modifications right now and we need to put the new software through the usual testing process.
• If you apply this update and you have third-party (non AppStore) applications from Cydia and Installer that you rely on they will stop working.
• 2G (1st gen) iPhone users who cannot wait for the new PwnageTool or QuickPwn can safely “Update” to 2.2 using iTunes, this will preserve the existing activation. However “restoring” to 2.2 using iTunes will return the iPhone to the unactivated state. If you are in any doubt just wait. NB: This works for 2G ONLY.
• The use of SIM-Proxies (small circuit boards/chips that sit underneath the SIM card) to provide GSM/UMTS service on your locked iPhone 3G: early reports suggest that the 2.2 update disables the functionality of these devices.
