PS Mobile was the fastest way that games could be published for Playstation-Certified devices, including the PlayStation Vita. When Sony opened up developement to indie game developers but removing the sign-up fee, there was a collective sigh of relief.
Recently, Sony announced the discontinuation of the PS Mobile program, with the store ending July 2015. SiDefect was in the process of being ported to the system when this announcement was made, proactively killing the progress.
The PS Mobile program was a good program that suffered due to failing hardward. hopefully there is a similar program that will help developers become part of the playstation network.
