Recycled phones you can throw away without guilt

Guess what, someone in the US is coming up with a US$10 phone that is only as thick as a stack of three credit cards pressed together, and is made from recycled paper products.
The phone is disposable too -- after 60 minutes of use, and you can charge the extra calling time via credit card.
So, if you ever see an ad offering mobile phones at nutty prices (some time in the third quarter of this year but were just guessing) you'd be right to guess it's for a Phone-Card-Phone.
