The MiFi mobile router, that little dinky box that mobile bloggers and road warriors have been ranting and raving about, has a teeny weeny problem. If someone wanted to, they could find out your exact location. Every MiFi is GPS enabled, and all a hacker has to do to get your coordinates is send you a specially formatted hyperlink that once clicked will pass the MiFi’s WiFi security key and exact position in clear text to the attacker. Men cheating on their wives, terrorists, and children cutting class to smoke pot and have unprotected sex be warned.
Just go back to using a dongle, and if you really want to connect your iPod Touch while on the go then you should just sell it and get an iPhone. Nokia users can use Nokia PC Suite to tether, the Palm Pre now has tethering, and I think Windows Mobile has a MiFi like feature that’s been built in for several years now. Of course your mobile phone’s battery will die faster than a Haitian stuck under a fallen building (is it too soon?), but at least no one will know where you are.
