And yet those are all 32 bit ARM cores. Which in some way was "unavoidable" as I don't know what viable alternatives existed for a phone SoC in 2007, though someone can correct that. ARM1132? That is not a core I have ever heard of nor can find any reference to. I assume it would be some ARMv6 ARM11 though, a uarch that was already quite mature by the time the iphone rolled around.
