Attachment A discloses the size and mass of the Starlink V2s with SCS capability (SCS = Supplemental Coverage from Space, this is FCC's name for this new capability of connecting unmodified cellphones to satellites). This shows that V2 with SCS capability has two versions, one launching on F9 (designated "F9-3"), one launching on Starship (designated "Starship-2"):

tables below present illustrative information for proposed form factors of SpaceX Gen2 satellites with SCS capabilities: one of which will be launched on Falcon 9 rockets and one that will be launched on Starship. For convenience, these satellites are labeled satellites F9-3 and Starship-2, respectively, following the naming convention SpaceX used for its authorized Gen2 satellites. Note that to better reflect a non-maneuverable satellite in a tumbling deorbit a 0.5 scaling factor has been applied to the area-to-mass ratios used with NASA’s Debris Assessment Software (“DAS”). Further note that while the specific dimensions of the bus of the Starship-2 satellite is larger than the Starship-1 satellite, reflecting a deployed SCS antenna, the DAS analysis of the Starship-2 satellite is identical to the Starship-1 analysis that the Commission approved in the Gen2 Order because the area-to-mass ratio used for the analysis is the same.

So we now have 5 different Starlink V2s:

Note the V2 Mini with SCS capability (F9-3) has a mass of nearly 1 metric ton, 170kg heavier than regular V2 Mini (F9-2).
