January 21 - 3:25pm EST   Polymer Vision this afternoon revealed that it has begun producing the Readius, a device billed as the world's first phone with a foldable display. Even more advanced than Amazon's Kindle, the device uses a 5-inch e-paper display that not only replicates the sharpness of ink but tucks into the main body, creating a much smaller profile than any e-book reader. It also serves as a full-fledged phone: thanks to tri-band HSDPA, the Readius can make calls and connect to the Internet in the US and most other 3G-capable areas of the world. This allows live RSS reading as well as e-mail and other real-time information. [full story]
