I think one of the reason could be, because to flash actual cheep Nokia phones like the Nokia 1200, you need a DCT Flasher like JAF. These is not sooo cheap like just getting a serial cable for 2€ and the phone for other 5€. And Siemens .... Siemens is dead. When start doing something on products that are not produced any more, you get the situation that is now with the com on air DECT PCMCIA Typ 2 cards.
