Hi Radek

Very original - considered it is a smart phone. I have trouble writing 
retro smart phone. ;-)


Inspired by your choice, I would add that the wood ought to be 
waterproofed/marine plywood - or at least plywood with waterproof 
adhesive. The (ply)wood might to be "painted" with natural linseed oil 
(without tar) [1] to keep moisture out. Moisture will convert radio 
signals to heat.

Maybe one can make self-made plywood from thin teak sheets or...

The reason for plywood is, that it is - or is supposedly warping stable. 
And plywood has a lot less chance of cracking, because of the fiber 
criss crossing.

For (ply)wood:
* strong
* floats if dropped in water ;-)

* strong heat isolation - the battery and other chips might sometimes 
have heat problem


Do you know that wood is a composite material? [2]

It is made of polymerized sugar; cellulose (the strong fiber, "iron 
rebar"-feature) and lignin ("concrete"-feature) that keeps the fibers 
together. Heartwood has high lignin content.  Especially ironwood and 
mahogany has a very high lignin content, which is why it has higher dry 
density than water. Higher lignin contents means higher moisure 
resistance and that is why heartwood is the choice for wooden window frames.
