On: A cellphone with no flips, no folds - just a very low price

The Motorola F3 has been selling at this price point for a year I believe - http://en.wikipedia.org/wiki/Motorola_FONE_F3

You can pick up pay as you go Nokia S40's for £20 or so these days too.

The tricky part is designing a UI for illiterate users.

Do you know if the F3 will work with T-Mobile in USA?

There are two versions of the F3; the 850/1900 MHz variant works with any GSM carrier in the US (AT&T/T-Mobile/etc).

I bought one for $40. The calls sound clear, the battery lasts for 5+ days, and you can run over it in a car without breaking it.
