So just to clarify, are you really after something with no possible way of making or taking a call when a phone is shut, rather than it having no external buttons what-so-ever? Only ask as there will be some which could have external volume buttons but wouldn't allow a call to be answered (ie turn off any key answer).

Also, are you after something newish (eg colour screen, camera etc) or would somethign from yesteryear be ok so long as it's got no buttons at all outside?

If you go to the Virgin site then there are some pretty basic clamshells which look like they have no external buttons.

What about using any phone at all that you like but having it inside a hard case? Surely then no buttons doesn't enter the equation???
