Sorry for doubting you all, I have proof in my hand that it works on North America GSM Carrier. I had my VZW 9530 unlocked and inserted the AT&T SIM I have and viola, it shows AT&T under carrier and I was able to make a call. Once I get home I will insert my TMO SIM card, which I have in my 8320 and start using the Storm on TMO's network. I know you need proof, I will upload pictures once I get home. But take my word for now, it works, and VZW has the unlock code don't let them tell you otherwise.
