Got chance to get a brand new in the box brand new in the box Quad Core HSPA plus S3 ($450). I've got about 6 hours to decide. I already have the ATT LTE S3. In my part of Florida, LTE ATT speeds are amazing and rock solid reception. But opportunity came up for me to get a Quad Core S3 international version. My brother's friend just got back from Asia and he's got one to unload to me if I wanted it for only $450. I think he gets a few phones for heavy discounts since he's in the industry. I know brand new they usually got for $550-600 on amazon. Yeah, I know advantages of using the $10 unlimited data plan on ATT. But I really only pay $22.70 (after 24% corp discount) for my LTE data plan (5GB and than throttled). You do not get discount for $10 data plan. What would you get? The duo core LTE version or Quad Core HSPA version. Price difference is only $50 for me. I already own the LTE S3 version and can probably resell it for at least $400 easily, maybe $450 also.
