Как снова включить internet tethering ан прошивке 3.1.2?


С помощью internet tethering можно использовать интернет подключение iPhone на десктопе или ноутбуке. Ниже приведено небольшое руководство для продвинутых пользователей. Всем остальным мы рекомендуем подождать новой версии PwnageTool или другой специальной утилиты.

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.
