Any carrier unlocked iPhone will work with all the carriers in South Africa. The frequencies available are GSM 900/1800 and UMTS/HSDPA 2100 and all the carriers offer micro-SIMs if asked.

In fact, that's true for the rest of Africa too, where you're pretty much guaranteed to find at least one GSM 900/1800 network wherever you go and in many cases a UMTS/HSDPA 2100 3G network as well, though the coverage might not be as comprehensive as it is in South Africa.
