Factory Service Mode w/o Dongle?

Wasn't there a way to get in FSM without USB Dongle but with CFW?
I want/need to remarry my BR-D but for doin that, i need to get in Factory Service mode.
BUT I can't buy a dongle because if the guys at the toll (right word?, i mean the border of a country :D) see that I've purchased a dongle i'll receive a cease-and-desist order and need to pay 5000€

I've heard of methods like using a mobile/ipod/iphone
but i "only" have a Nokia 5800 Xm and (ironicly) a few Sony Ericssons
