I have used the quadrature demodulator block on GMSK (which is also
non-continuous phase) with great success.

The clock recovery block will resample the data stream at the data
clock's frequency, yielding a stream of "soft bits". These can then
be fed to a bit-slicer to produce a stream of binary '1's and '0's.
