Enable MMS on the iPhone without Updating to 3.1

September 27th, 2009

For those of you who don’t want to update to firmware 3.1 for whatever reason, but want MMS- follow this guide.

iTunes wants you to update your iPhone to 3.1 before letting you update the carrier file to enable MMS. Many people are asking how to get the the latest carrier file without updating to 3.1. You don’t need to be jailbroken to do this.

Here’s how:

Get the latest version carrier file (.ippc) 5.5 to enable MMS HERE

On Windows it may rename the file to .zip to just rename it back to .ipcc

Make sure itunes is not running

Windows – open up a command shell and type in:

For 32-bit Windows
“C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1

hit enter

For 64-bit Windows
“C:\Program Files (x86)\iTunes\iTunes.exe” /setPrefInt carrier-testing 1

hit enter

If you copy and paste the commands they won’t work. After you type the command and hit enter it shouldn’t give you any error or any indication it did anything.

Mac – open a terminal and type in..
defaults write com.apple.iTunes carrier-testing -bool TRUE

hit return

This should now allow you to update your iPhones carrier (.ipcc) file in itunes 9 by pressing and holding shift while clicking the update button (Windows) or Command-Update (Macintosh) in itunes. Choose the .ippc file you just downloaded and install it.

You will need to reboot the iPhone after you install.

You’re all set!
