The international has been out a lot longer than the US version. And they are not compatible due to different hardware.

While it may seem they're all the exact same, the various us versions have different radios and other carrier specific stuff. And remember, the international gs3 has been out since may, of course the devs are used it by now. The non-int versions really only just came out a week ago.

The international Galaxy S3 (i9300) is practically a different phone from any of the US variants, in terms of hardware. It uses a different SoC (system-on-a-chip; different processor and graphics processor) and different cellular radios.

The US variants are also all different in the regard that they each run slightly different software by default, but the only hardware difference is in the cellular radios. They share the same SoC, so it's feasible to port ROMs between them without too much work. This also applies to the Canadian variants and such, as they share the same SoC and hardware as the US variants, with the exception of those cellular radios.

The Verizon version is the black sheep in that it has a locked bootloader, and currently ROMs that utilize a non-stock kernel can only be flashed to it (and work) if a workaround is used.
