Sounds like a KDE fork of the UbuntuPhone (http://www.ubuntu.com/phone).
KubuntuPhone?
In theory it would be possible to create a "TrisquelPhone", by stripping all
the nonfree components out of UbuntuPhone, just like what's done to Ubuntu to
create Trisquel. The problems would be the same as for Replicant; it would
only run on a handful of devices (whichever kinds the TrisquelPhone
developers had to benchmark against), and would be fiendishly complex to
install, even for those of us who have got comfortable with install GNU+Linux
on ex-Windows PCs.
The FSF has a campaign to gather information about efforts to restore full
software freedom to Android/Linux devices:

What would be really sick is if somebody could provide some simple
instructions for hacking an iThing and replacing iOS with a libre OS. I think
whipping out a liberated iThing at tech events would definitely make a
statement ;)
