Fantastic script TechnoLover, it works very good on t&l stock 2.3.6.
Nor ClockWorkMod Recovery neither AmonRA 2.2 manage to backup the sd-ext after applying the script; is that normal? I can use dd on my linux box, but it's strange that recoveries aren't aware of the partition (AmonRA prompt me an error and Clockwork simply say "no sd-ext found").
UPDATE: The problem probably was with my ext3 partition. Just using AmonRA's function "repair SD-ext" did the job (but i had to redo it on every recovery reboot). Not tried ClockWorkMod, but i don't remeber such a "repair" function on it.
