I currently have a student discount with ATT and am afraid of losing it if I renew my contract through walmart. I'm looking at purchasing the HTC one x. It's currently 120$ at walmart instead of the 200$ at at&t. Do you know I purchase it from a 3rd party retailer and choose to renew my plan if I will lose my discount. What other if any problems are there renewing a contract at a 3rd party retailer like walmart, bestbuy ect.?
