Yep, just called. Multiple reps have said they aren't able to pre-order the Note 3 at full retail, unless you enroll in the Edge plan. They said to purchase at full retail and remain on unlimited, you need to wait till the phone is actually out.
You might just want to double check that the rep you ordered with didn't change you over to the Edge plan despite telling you otherwise (you know how unreliable csrs are). That or I guess you got lucky.
