Samsung has launched the SPH-G1000 and SCH-G100 gaming phones in its native Korea, featuring a dedicated gaming joypad and buttons and built-in vibration capability. These aren’t likely intended to be serious threats to dedicated mobile gaming hardware like the PSP or DS, but that doesn’t really matter anyway, since they’ll likely not be released outside Korea.
