and specifically this post in that thread is what I used to purchase my unlock code...

I'm now able to use any SIM card, North American or otherwise, to roam onto that carriers GSM network.

I understand, however the thing with Sprint is somewhat different. I went to the Settings -> Security and it says, "This phone is SIM unlocked."

So I put in an AT&T SIM card, switched the system to the GSM only mode, it tells me that "No Network Detected" and the phone status is "No Services."

Then I did a manual search on GSM networks, it still refuse to find any GSM networks. I swap out the AT&T SIM and put in a T-Mobile SIM, still the same result.

I thought my GSM radio is no good but under SIM manager, I can actually see the phone numbers and text messages I stored on the SIM card. Also I can hear the famous GSM pulse buzz in our old office phone.

Also in the phone there is an PDF titled "International Usage". I opened it and I saw something that says "Note: When in the United States, your device will only operate in CDMA only mode, domestic GSM networks are NOT accessible via this device."

Sounds like me that it's a software lock rather than a subsidy lock. Of course I could be wrong too. I don't have an non-US SIM card so I can't try it out if it's unlocked or not. I will be traveling to China in 2 weeks and I guess I will bring the phone with me to give a try.

Again, Sprint did this on purpose I am sure, after all whom would want someone to buy a phone for CDMA system and use it on a competitor's GSM network anyway. Oh yes BTW, it does NOT has US 3G band (UTMS 2100 only) so, EDGE in the States at the most.
