Hi Mychaela, community,

I am reaching out here to share some of my findings regarding the 
K2xx-series of Sony Ericsson phones.  TL;DR, Sony Ericsson K205 is 
another Calypso based phone, among with the known K200/K220 pair.

I bought one for a reasonable price and disassembled it to take PCB 
photos.  I am not posting them here nor anywhere else simply because 
it's exactly the same PCB as in K200.  The only thing that makes K205 
special is the housing, which is different from K200/K220 - that's it. 
Not counting the firmware, which is likely ~99% identical too.

In any case, I dumped the firmware for the sake of completeness and 
uploaded it to a friendly Sony Ericsson modding server's storage:

I have already edited the wiki page in osmocom-bb project accordingly:

Please find a patch for freecalypso-tools attached.
