Hi,
I'm impressed by the size of the battery....
The only piece of information I can give you is that it might be due to
the Nokia built in security. Nokia usually has some proprietory stuff
built into their cables, to prevent people from using standard cables on
their phones. I suggest building up a cable from scratch. It is fairly
easy to do, and would cost about R10. If as much. You could source the
components at any electronics shop... (Maybe a bit difficult in
Saldanha, but try TV and Computer repair shops). You could also buy
general components from the following companies, and I'm sure they would
be able to ship to you. (Depending on how much you are willing to pay
for shipping I suppose). The connector part numbers for serial ports are
usually called DB9 male and female.

down, but should go up again soon)
I hope the information help you. If not ... mabye next time.
Greetings
Henk
