On the Nokia CA-42 data cable

Do not buy the local brands. They are liable to not work
with a large variety of Nokia models.

Do not spend hours, days, fortnights wandering the web
for solutions. Just buy the original cable and it will
all work quite magically.

And above all, to save a few bucks, do not believe any
of the "solutions" you may see on various forums. They
are not generic in nature, and are almost certainly
going to fail for your situation.

You have been warned!

So go out and buy the original. It is available for
Rs 1700 odd at Link Telecom on Camac Street, a Nokia
priority dealer. Most other NPDs in Kolkata dont keep
it.

The other important point is, do NOT plug the cable in
before installing the latest version of the Nokia PC
Suite. In fact, one should completely ignore the software
driver that comes with the cable. The correct sequence
of steps is, and there is no leeway for errors ...

1. Install Nokia PC Suite.
2. Make sure the phone is not locked
3. When prompted, plug in the cable and then attach the
business end to the phone, in that sequence.

The only other thing you may have to do is set the packet
data access point in the One Touch Access settings.
