: Yes you do.. Have a look at their site's product page HERE
EDIT: I just saw you have a slim, so to be 100% solderless for now, you need to have an E3 flasher. If progskeet release a NOR clip, then you could get that.
For 100% solderless compatability, use the following:
Progskeet = NAND models only CECHA - CECHG (old phat models)
E3 Flasher = NOR models only CECHH - Everything else.. (new phats + all slims)
This is because neither work 100% solderless with all PS3's for now
. It seems like E3 will have NAND support before Progskeet supports NOR (only for solderless, if you can solder they both do them all).
