I have a quick question regarding upgrade eligibility. The primary line on our account (my brother's) is eligible for a full subsidized upgrade. He bought a 3GS at launch last year. I understand that a primary line is eligible to upgrade when the plan is above a certain amount. All of my family members have iPhones. I bought an iPhone 4 on launch. As of today, my line is the primary line. Will I be eligible for the iPhone 5 next year at the fully subsidized price? My brother doesn't care about upgrading this year. Thanks.
