How To: downgrade to previous iTunes software

Many people running into trouble running the iPhone Utility Client (iPhuc) report that using an earlier version of iTunes' MobileDevices private framework will fix their problem since it would seem that iPhuc was designed to run under iTunes 7.4.2. What can you do? iPhone developer "core" has come up with a simple solution.

Over at his WickedPsyched site, he's put up full instructions on how to keep the minty-fresh goodness of the latest iTunes install (currently 7.6) yet temporarily revert back to to 7.4.2 when you need to run iPhuc.

The steps include downloading an old version of iTunes, backing up your current MobileDevices framework, copying the 7.4.2 framework to your system library, and using a simple shell script to toggle between the new version of the utility and the old one when you launch iPhuc.

I can't get this to work with 7.6 or 7.4.2 framework. Under 7.6, I get "Illegal instruction" (after a while) and under 7.4.2 I get a segmentation fault (again, after a while). Any thoughts?

It seems as if 7.6 has also broken the ability to add custom ringtones to the iPhone through the drag-and-drop method. I wonder if this could be restored by using an earlier version of iTunes? Anyone know?

I already added a custom ringtone by running this method (if you have a mac, that is):

1. Create your ringtone file in the proper format (plenty of tutorials out there with varying methods)
2. Change the extension of the file to .m4r
3. Copy that file into your ringtones folder (if you already have a custom ringtone just search for that folder, otherwise create a folder called ringtones)
4. Double click the ringtone and when iTunes opens it up, it should show up under the ringtones heading and allow you to send it to the phone

Hope that works out for you, I added on my oh so special CTU ringtone using this method and it worked just fine for me.

Oh, and I forgot to mention that I'm running 7.6 iTunes and 1.1.3 firmware (and I've spent the majority of the last 6 hours trying to undo that)
