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)  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
* 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? 
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.
