The Nokia 770 has Bluetooth, which allowed (see previous post) me to connect to the internet. The connection to internet can be created in two ways, one was by using my phone (A Nokia 6021), which worked without any problem (except for the money bit), or by using a bluetooth attached to a linux PC with some iptables magic.
Both ways work like a charm, but the second one is a bit difficult to configure. It would be nice if the Bluetooth via the PC would as simple as Bluetooth via a phone.
There is also a way to connect the Nokia 770 via wireless to the internet, but I don't have a wireless router, or accesspoint or some such to test it. I expect that that will work as easily as the phone bit.
