imFONE Bluetooth dongle lets you make VoIP calls from your cell

Usually we prefer to cover USB devices that are completely useless, but we'll make an exception for the imFONE, an intriguing new Bluetooth peripheral from Korean manufacturer Enustech (not to be confused with Anustech, makers of self-prostate-exam devices) that allows you to use certain cellphones as VoIP handsets. Now
Skype users with one of three cells that work with this peripheral can toss their crappy omnidirectional PC mics and low-wattage speakers in favor of the crisp,
clear sound quality that cellphones are known for (is that snickering we hear?).
