I was wanting to try this out but have a few questions.
1) I am currently on 1.0.2 using iTunes 7.3.x. I have jailbroken, activated, and restored YouTube using the method found here:
http://www.hackint0sh.org/forum/showthread.php?t=3658 (I believe this is the same PACAY script that is referenced by Step 2 in the instructions above)
2) I would like to undo the activation/jailbreak and then restore my iPhone using iTunes 7.3.x (which should put it back to its "factory" state)
3) Then I would like to upgrade to iTunes 7.4 and run the steps above to Jailbreak/Activate/Restore Youtube/Install Installer.app
Two questions:
a) Does this seem reasonable?
b) Is the PACAY script compatible with 7.4 and 1.0.2?
I reeeeeeeeally don't wanna brick my iPhone :-)
