iOS 与 Armv6 Armv7 i386

    [size=medium]Armv6 binaries are needed if you’re targeting iPhone3G (yes, they still exist, my co-worker uses one, can u believe it?);
Armv7 binaries are desirable if you’re targeting iPhone3GS/4 or iPad, since these new toys have Armv7 processors and, besides being able to rum Armv6 binaries, they probably will have a better performance using the better Armv7 architecture;
i386 binares are needed if you intent to run your code at the Simulator (ok, it is needed, right?!).[/size]
