JoikuSpot Now on Windows Mobile
The theory is that the program uses the data connection on your mobile phone–which is hopefully 3G. That data connection is made available over WiFi as a regular access point to other WiFi-enabled devices. Sort of, at least on S60, as it is only able to use an AdHoc network type, not infrastructure. This limits you ability to use it with, say, a Nintendo DS or Sony PSP. However, it works great with computers.
JoikuSpot is also currently 40% off: 15 Euros instead of the normal 25! While that’s still a lot of clams in U.S. Pesos, it’s still a nice investment. Where else are you going to get a portable WiFi router for that price?
