Hello!
I have the following idea, which should allow any mobile device with its
own IP-networking -- such as a Blackberry or a (hacked) iPhone -- to
offer connectivity to a compatible computer, regardless of the
service-provider's wishes.
The device needs to run some equivalent of natd... This way, all network
connections will appear to the outside world as originating from the
device itself. The device will connect to the general purpose computer
via Bluetooth (although wired connections may also be possible,
Bluetooth seems most standardized).
The "natd", running on the device, will intercept and properly proxy the
connections on behalf of the computer. The computer will, probably, use
the specially-created tun-interface:
tun <-> bluetooth <-> network address translation on the device <-> IP
Note, that this would be different from using the device as a "modem" --
doing so, typically, makes the device unusable for anything else for the
duration of the call, and requires the service-provider's cooperation
(and thus higher fees). My way, if you can browse the 'net with the
device's browser, you'll also be able to do so from a laptop sitting
next to the device...
If anyone wants to try it, I'd be willing to donate a Blackberry and/or
some money to the cause. Please, respond off-line, if you are
interested. Serious inquiries only. Continuation of the technical
discussion should, certainly, stay on the mailing list (please, CC me as
I'm not a subscriber).
