This SWAP Nova Keychain Phone is a 2G (GSM/GPRS) handset smaller than a box of matches. It’s produced by the same people who do the watch phones, so it’s got pedigree, although it’s actually more mongrel than pure bred. Comes with stylus, microSD slot and a recessed direct connect USB plug. You can either hang it round your neck or on the key fob, and wonder of wonders you actually hold it to your ear to talk. Amazing. The thing is due out later this year at around £199.00. Check out the video for more.
