MMS hack for At&t still possible
In the 3.1 update the MMS and tethering hack did no
longer work, although some people reported that the
hacks were still working for them after the update.
Aaron Krill, the man who discovered the hacks, is
back again but with just the tethering hack. Bellow
are the instructions on how to do it, the hack only
works for At&t.
First make sure you have
iTunes 8.2 or 9, your iPhone is running OS 3.1 and
you have the modified version of the At&t
carrier file “ATT_US.ipcc” download the file
here.
You must enable IPCC
updates on iTunes with these steps:
MAC:
1. Make sure iTunes is closed then open up Terminal
Open Terminal. Applications > Utilities >
Terminal2. Paste everything bellow
into the box:
defaults write com.apple.iTunes carrier-testing
-bool TRUE.
Windows:
1. Make sure iTunes is closed,then go to start>
run> and type in the box CMD
2. Paste everything bellow in to the box, by right
clicking on the box and hit enter.(shortcuts wont
work):
“%Program Files%\iTunes\iTunes.exe” /setPrefInt
carrier-testing 1
Now you must update the carrier file with these
instructions:
-
Open up iTunes and connect your iPhone.
-
Click on your iPhone in iTunes.
-
Windows: hold shift and click Check for Update.
-
MAC: hold alt/option and click Check for Update.
-
Select the ATT_US.ipcc you downloaded earlier.
-
Once everything looks clear reboot your iPhone.
-
MMS should be enabled.
It is not guaranteed that
this will work because At&t is well basically
fiddling about with it right now.
