Well, I'm looking at a couple tweaks which may make the SD Card folder hack obsolete in probably 90% of the cases. I'm also testing out a couple little applets which like some stuff written for the DR1000S will let people install/uninstall the patched files at will.
I'll see where it takes me.
That said, if you can follow the directions of setting up the SDK and get the emulator running for v3.0 of the iOn SDK... you are past the hard part. If you can't, I'd probably wait for patched binaries.
EDIT: If you feel uneasy about any of this, don't push yourself. I forgot to mention there are risks in modifying the firmware to get this to work. I had to mess with the emulator for a couple hours until I was confident enough that I wasn't gonna brick my device (the app I have to replace is part of the core firmware). I do software development for a living, and I still couldn't breathe until the iRex finished rebooting... even though I'd seen it work in the emulator multiple times.
