Kyoceras are nice because they're not nearly as locked-down as Fujitsu. I've got an F-03L and I wanted to hack it (Qualcomm 210 so I could put pmOS on it), but it looks like they removed everything - fastboot, recovery, even edl(...how?).
Opened it and tried to solder UART to it, but sadly ended up ripping pads off (even under the miscroscope!) because it was so freakin' tiny.
Unfortunately it has an NTT (Docomo) SIMLock (ironically enough I have a SoftBank SIM but can't use it in EU because foreigners apparently can't get roaming according to some laws I've read).
I wish I used 200% of my brain and brought it to Docomo branch when I was in Japan to remove the simlock. It worked with an iPhone (so I got it 40% cheaper than usual) so...
I love keitais though. They even support stuff like Osafu-Keitai so you can use them for public transport (if you live in Japan...) or payments, they fit in your pocket, have physical keyboards and last forever on a single charge. Absolutely peak phone design.
