VPhone is a wee "phone", surely the most wee of them all. It has a 1.54-inch touchscreen display, Bluetooth, FM radio, pedometer, 128MB (megabytes!) of storage, a heart rate monitor, some social network-monitoring apps, and a choice of "simple and stylish" black or silver trim. The radio's quad-band GSM, so if you can get your hands on one it should work on T-Mobile and ATT in the US.
Yes, there's also a 3.5mm phone jack. The Verge's Ashley Carman:
Some of you might read these stats and think they're sad. I kind of agree, but I just really love how little this phone is, so it cancels out depressing spec reality. … The S8 appears to only be available in China, so we, once again, will have to keep dreaming. I'm trying, everyone! I think if we dream hard enough we can force these cool phones to appear in front of us. Will it.
Agreed! It's a curious device that seems more a chunky call-enabled smartwatch than a fully-featured mobile–and the English is a bit ropey on the product page, so it's not really clear if it can make voice calls without a BT connection to another device. Carman points to this 2.45"-screened crapgadget as the smallest bona-fide smartphone on offer; the ancient Sony-Ericsson Xperia X10 Mini, despite its age, is probably a better bet in the 2.5"-ish range.
