I have one, been using it as a companion phone alongside my XA2, but failed to spot that one of the obscurely named updates brought the device up to Android 11 (59.1.A2.28).

Is this boned as far as installing SFOS on it?

Ideally, i'd like to buy an Xperia 10 iii, migrate my Android account to that device and install SFOS on the 10 ii i already own...
