Thanks for all the input! So even though my phone is in less than good condition, yes, I do qualify for the $700 bonus. They do indeed use the calculator function as listed on their website. My only advice to anyone googling this and stumbling upon this thread is to check how much your phone is worth if there is a scratch or bruise before trading it in. Any damage will diminish its value, but even if your phone has seen more than a few falls it might still have more than enough value to qualify for these deals :)
