Bluetooth on a mobile phone is an amazing invention - wireless headsets and hands-free calling alone would make it worthwhile. However, for over a year I've had no luck at getting it to work as a modem for my various laptops.
Until today. The new netbook, with a bit of tweaking and twisting, is now making L2TP connections via bluetooth and the ORBIT2, and thence via O2's network, all the way to the company network. This has bugged me for so long, and now it's working!
The real answer lay in using Internet Connection Sharing on the phone - I could easily get the PC to see the phone, but never had any way of getting info in and out. This last step fixed that. Naturally, it isn't necessarily that easy - the bluetooth settings on the laptop take a bit of getting the head around, but I have satisfied myself that the functionality is reproducible.
The worst bit, so far, is the absolutely appalling lag - ping times in the 400-600 ms range mean that anything like a complex web page is going to load very slowly. At that sort of rate, I'd almost be better with an old 300 baud modem on a POTS line.
