Thought WiFi spectrum was congested now? You ain't seen nothin' yet, because SIM card provider Sagem Orga has hooked up with Telefonica to develop a marvel of modern technology called "SIMFi" that combines -- you guessed it -- WiFi with a run-of-the-mill SIM card like you'd slip in your cell. In practical terms, this means that you're able to turn virtually any phone (or "classic handsets," as the company calls them) into a WiFi hotspot accessible by authenticated laptops, MIDs, and miscellaneous wireless gadgets in the immediate vicinity. Frankly, the concept is downright brilliant in its simplicity -- never mind the fact that we had no idea you could fit WiFi circuitry into a 25 x 15 x 0.76mm footprint -- and we're excited for what this means for the future of tethering, assuming carriers can keep up with the spectrum demands. MiFis and Overdrives of the world, you're on notice. Follow the break for Sagem Orga's full release.
