Check out Technograph's rundown of JoikuSpot Light, an interesting app that turns certain high-end Nokia phones into portable wi-fi hotspots.

Imagine the possibilities! If an HSDPA-capable phone's battery can survive a marathon session, and has a clear signal, then perhaps we're talking about several laptop gamers connecting to their favorite online games through only one phone? Of course, with the battery lives of high-end phones and reliability of mobile connectivity as they are, it could still be a remote possibility. Still, JoikuSpot, once perfected, could mean more possibilities beyond the one-computer setup that still prevails among mobile connectivity approaches today.
