i can't just flash the PeanutButta Jelly Time initially?
Yes, you can. Just download one of the imnuts Voodoo kernels from here:
https://sites.google.com/a/imnuts.net/android/kernels (the ones that say "imnuts" are TouchWiz, the others are AOSP).
On first boot, it'll automatically convert to EXT4. Just make sure if you want to switch back to a non-Voodoo kernel, you disable it *before* doing so.
And yea, these kernels will put CWM 3 on your phone, which will only work with newer zips. Personally, I just flash back to CWM 2.5.x (the 3-30 FIX version) after installing this kernel since it will work with amend and edify scripting. But remember, to do so, you have to Odin the tar version of the recovery, since the zip version uses the amend scripting that CWM 3 doesn't support.
Oh, and on Voodoo specifically, if you're not susceptible to the placebo effect, you're not going to notice any difference. If you are susceptible to placebos, prepare for a much "snappier" phone!
