I did this on my new Mytouch and 3 Mytouch 3g of my friend I charge them 20$ lol.

If you want to change rom just do PROCEDURE E.

*Original partition value of doing a Fat32/ext2/linuxswap : Linux swap-32mb / ext2-500mb / Fat32-remainingsdcard space

(anyone can confirm this?)

On mine I did Linux swap-62mb / Ext2-1gb / Fat32 is the remaining of my 16gb class6 micro sdcard space.

I use some linux bootable cd that I formatted any partition just by sliding a bar, no more typing command.
