I was kind of wondering. I hope sprint does not take the GSM chip out of the Samsung 4 like the S3. If they do it would not make it a world like Samsung meant it to to be, Big Red has a GSM chip in there Samsung 3. Take note Sprint.

That world roaming doesn't require a whole extra chip (at least not a major one.) Most of the support is built right into the main Qualcomm chipset. But it does require some extra circuitry (usually very tiny parts, which may or may not be built into larger parts that would be there anyway.)
