We haven’t seen this one since April, but the sWaP NOVA keychain phone will finally hit the UK this October. It claims to be the smallest smartphone in the world at 68.5mm x 38mm x 16.2mm in size, while weighing just 43 grams.
That’s a touchscreen display and at that size it’s a good thing they include a stylus. Battery life is just 82 hours of standby time and 150 minutes of talk time. It can be charged via USB and you can still browse the Web via WAP.
