Thank you VICODAN! I finally got around to rooting my wife's shift because of this guide. The videos were very helpful. The only thing I was missing was the Blue Moon within reach. It would have helped, I'm sure.
A quick mention: under the rooting 2.2 instructions, the link to the Visionary apk is dead. I looked around on the forums to find another one, and then totally facepalmed when I saw it sitting open in the shift-rootkit.rar that I had downloaded from the 2.3.4 instructions. Might want to mention that it is already included if you started from there!
Edit: Oh yeah, another facepalm. Spent a good half hour trying to get the bootloader to find the PC06IMG.zip file, it kept skipping over it. It never clicked that this is the stock 2Gb microSD. And, with 2Gb or less, you can use either FAT16 or FAT32... turns out I just had to reformat the card and poof! It worked. Facepalm... it says that right on the front page at the end of the 2.3.4 instructions.
