It's not just the big mobile phone manufacturers that are interested in developing ultra-low-cost handsets for emerging markets. Electronic component maker TTP Communications has announced a new "reference blueprint" for a full-function cell phone with an end-user cost of under $20. The phone design includes software such as email, camera and multimedia support, even voice recognition, along with interfaces for connecting external hardware.

TTP claims that further improvements to production processes should bring the costs down even further.
