What you said is correct BUT i realised that actually the problem is this: when the mmc is in the phone you can't rename or move anything from the folder "address book" and also you can't copy anything into this folder (of course after you have removed the hidden attributes). Even if it is not "read only" before you put the mmc in the phone, it becomes "read only" as soon as you put the mmc in. I guess that only the "patchers" can at least tell us if something can be done about this.
@ all patchers and not only...
Tell us at least if this can be changed or not. ThanX
