These are the names of the twelve apostles: first, Simon (who is called Peter) and his brother Andrew; James son of Zebedee, and his brother John; Philip and Bartholomew; Thomas and Matthew the tax collector; James son of Alphaeus, and Thaddaeus; Simon the Zealot and Judas Iscariot, who betrayed him.
As you can see above, the initial release of Apostle 12 was Judas Iscariot, who betrayed Jesus for 30 silver coins. Filled with remorse, he later hanged himself. (Read Matthew's account of Judas' end by clicking here.) So I think it can be literally and correctly stated Apostle 12.0 contained a fatal flaw.
Apostle 12.1 was released after the resurrected Christ had ascended to heaven but before the Holy Spirit was poured out on Jesus' followers on the Day of Pentecost. Apostle 12.1 was Matthias, a pretty substantial upgrade for Apostle 12, and initially quite well-received throughout the user community. (Matthias' story is in Acts:1.)
But you know how finicky some users can be. Even though Matthias performed all functions splendidly and completely satisfied most users, there were those who tried to discredit Apostle 12.1. These naysayers suggested Apostle 12.1 was rushed into release without proper beta testing, noting only one other candidate—Justus—was ever even considered for release. And then there's the fact Apostle 12.1 was the only version of the Apostle series ever released without the Chief Information Officer's firsthand approval. That is, Christ was already in heaven and the Holy Spirit hadn't yet descended, so it fell to Apostle 1, Simon Peter, to authorize the release.
So what did the Apostle 12.1 naysayers really want? Apparently they wanted Apostle 12.2. To overcome their objections, Apostle 12.2 would need to be personally approved by the CIO. And though it was several years later, the CIO (Jesus Christ) finally did personally approve the release of Apostle 12.2.
Apostle 12.2 was a complete overhaul of the original Apostle 12 concept. The CIO called Apostle 12.2 the Apostle to the Gentiles, and authorized his release as he journeyed to Damascus. During beta testing, Apostle 12.2 was code named Saul, but eventually was released as Paul throughout Asia Minor and Europe. Initially received with significant skepticism by the fanboys of Apostle 12.1, Paul ultimately became the most successful release ever of the Apostle 12 series.
