So I saw this idea on this site and trying to figure out how it will work. Buy iPhone 5 for $199 Sell iPhone 5 for $600 ish Buy iPad mini for $459 Total cost out if pocket $59 Now comes the plan and how to set it up. Mobile sharing plan for X data. And iPhone is $40 a month yet tablets are $10 a month. If you buy the iPhone 5 for the sub price and then sell it but keep its commitment how do you change the $40 a month to $10 without getting hit by a early termination fee?
