I've got a dual G5 PPC

I downloaded a jailbroken custom restore ispw firmware from an oregonstate.edu page and iTunes announced that it was incompatible.

Anyone else with a Mac PowerPC have an incompatibility problem with custom firmware made by an Intel Mac?

You probably downloaded the wrong one. There is a separate 3G and 3GS firmware.

I downloaded a jailbroken custom restore ispw file that was upped early today.
I've edited the original post to make that clear. Thanks

UPDATE: According to planetbeing's twitter page, the devs are working on the PowerPC bug -

There have been some unsettling posts in these parts, lately.
I'm going to wait for the nice-and-easy foolproof everything's gonna be allright, baby jailbreak edition.
