For less experienced users reading this.... The SkyRocket Roms werk on the T989 or Hercules SGS2.. all except the kernel which makes screen as well as gps orientation backwards. However I included the SkyRocket kernel so there should be no backwards orientation problems. Not all TWRP versions will likely be compatible. some versions of CWM are definately compatible as well just saying I use TWRP for the preload wipe feature .
