No, it was both. Both days were used for different purposes. You still see a remnant of this in the Eastern Orthodox fasting rules: fasting is always relaxed on both Saturday and Sunday, and during Lent the full Divine Liturgy (Eucharist), which is prohibited on the fasting weekdays, is sung on both Saturday and Sunday. When the Greeks learned that the Roman Church fasted on Saturdays, they made a big stink and tried to reprimand them for it (see the Trullo Council). They were wrong to make a fuss about it, but this all goes to show that Saturday was retained in the beginning (and dropped in the West because Sunday was more important), but Sunday was also added from day one. Biblical proof is that the disciples were all gathered together the Sunday after Easter, and then on Pentecost Sunday, and John the Apostle was worshiping privately on Sunday under house arrest when he got his vision of the apocalypse.
