  We study the phases of a two-flavor Nambu-Jona-Lasinio model at finite
temperature $T$, baryon and isospin chemical potentials:
$\mu_{B}=(\mu_{u}+\mu_{d})/2$, $\mu_{I}=(\mu_{u}-\mu_{d})/2$. This study
completes a previous analysis where only small isospin chemical potentials
$\mu_{I}$ were considered
