You are correct. The Oppo N1 is a GSM phone.
Sprint and Verizon are out for carriers. We could see AT&T or T-Mo carrying the phone, but don't get your hopes up. Oppo as a whole is still pretty unknown in the US.
My N1 has been running on StraightTalk using an AT&T SIM since the middle of November. I haven't had any issues so far with it, and I get unlimited for $45/month.
Remember though that there is no 4G on this phone. It can use up to HSDPA and HSPA+.
