Default Cell phone for homebrew ?

It always surprises me how little useful I can get out of these. I
used half the diplexer from a big old one as a filter for an 875 MHz
local oscillator chain for a 903 MHz receiving converter. And I used
the speaker from a more modern one to provide sidetone for a laser MCW
transmitter. That's it so far....
