Me and my sister are still confused about Next vs 2 year. We ended up letting the sales person talk is into getting Next, but now aren't sure if this is best. She still has 14 days to return phone and go to 2 year contract. My sister purchased the iPhone 6 under the next 18 month ATT plan which costs $22.92 a month. I plan on upgrading to the iPhone 6S 64GB under Next 18 for $31.25 a month. We had 6GB Mobile Share plan under 2 year contract for $70 but now we have 15GB for $100. I'm not sure if I'm doing the math right, but it seems like we are now going to be paying more a month. Instead of paying $170 we will now pay around $211 a month (including taxes and student FAN discount). The ATT rep said that the bill on contract will go up $20 and the 6GB is only 9 dollars less than the 15, but it still seems like I'm paying more, $170-190 vs $202-211. Am I right or am I missing something?
