It requires rooting/jailbreaking your phone and unlocking the bootloader, if you consider that an option. Otherwise, American carriers (except for T-Mobile) will freak out if you even mention running something other than what they put on the phone.

Ah, sure, that's fine (I ran Android on my iPhone once). Does it work perfectly otherwise, or are there any incompatibilities?
