I still doubt the Sprint version has a user replaceable sim slot for use on gsm networks.Note: Prior to using your Sprint Worldwide GSM/UMTS Data Services, you must establish and utilize your CDMA data services domestically on the Sprint Networksprint is a cdma carrier as we all know. the ONE on Sprint is not being touted as a world device. the micro sim slot is for LTE services, not to use gsm freqs.
one can do international roaming with this device as you can with other devices on Sprint.
just my opinion on what I've also read. it's all speculation until sprint users get this device.
don't want to make this into a big deal so I'll let you have the last word on it.
