It appears that "v03 Taptus Best" is a modified or hacked version of the original Phone Story game. The "Taptus" name might suggest that it's a version optimized for Taptus, a platform that allows users to play classic games on their mobile devices. The "v03" designation implies that it's a version 3 modification of the game. However, I couldn't find more information on what specific changes or features this version offers.
