eXpansys continues to offer the Sony Ericsson LiveView Bluetooth Cell Phone Interface, model no. SELIVE_EU, for $21.99 plus $3.99 for shipping. (allizwell2k10 via eBay has it for pennies more.) That's tied with our mention from last week and the lowest total price we could find now by $4. Compatible with most Android smartphones, this wearable Bluetooth cell phone accessory allows you to play music, mute calls, view incoming calls, and read texts, Twitter, and more without taking out your cell phone.
