Default Flash recovery: Epic4G or GalaxyS i9000

Hey guys, whenever I try to flash clockworkmod recovery it asks me if my phone is either an Epic4g or a GalaxyS i9000, which one do I select? I tried the i9000 one and when I would try to make a backup or install a zip from SD card through recovery it would give me a signature error, any help?

[EDIT]

This can be removed, I installed "[RECOVERY] CWMR 5.0.2.7 for the SGHI927(R) - Alpha" through Odin and it worked perfect!
