Can I buy an iPhone overseas?

I live in South Africa and the iPhone's prices are seriously high here ($812). I was thinking of buying one for so much less ($220) when I'm in Germany soon.

Will I be able to use the German iPhone back in South Africa? Anyone please help!

Yes you could use German phones in SOuth Africa because both of them use GSM network. If you want to be 200% sure then go ask people who work in telecom.
