Wanted Mac for iPhone Purposes

[jspre]

I am new to Mac. I am looking to buy an older Mac so I can use pwnage and other iPhone programs that run on Mac's only.

What should I be looking for? I've seen some G3's, G4's and G5's any where from $50 and up. Would these be ok for what I need? And which OS should it have, at least 10.0?

Any help would be appreciated,

Thank you
