We study the phases of a two-flavor Nambu\char21{}Jona-Lasinio model at finite temperature T, and baryon and isospin chemical potentials ${\ensuremath{\mu}}_{B}=({\ensuremath{\mu}}_{u}+{\ensuremath{\mu}}_{d})/2,$ ${\ensuremath{\mu}}_{I}=({\ensuremath{\mu}}_{u}\ensuremath{-}{\ensuremath{\mu}}_{d})/2.$ This study completes a previous analysis where only small isospin chemical potentials ${\ensuremath{\mu}}_{I}$ were considered.
