	I guess I didn't recall correctly then =P . I must have assumed that product engineer more or less meant designer.

	Interesting. I thought that sort of patching was something relatively new only done to the chips in sdcards and the like. I guess it's not new.

	Oh well. Thanks for the engineering details and info anyway =)
