Hello PeterAggs! I'm excited that you'll be getting an iPhone 5s. Since you'll be using the upgrade eligibility on your mom's line for use on your line, the best way to upgrade online is through My Verizon. When processing your upgrade, you'll be given the option to do so during the order. To my knowledge, Apple's site does not offer that feature. In addtion to that benefit, you may also enjoy reviewing available accessories to compliment your new 5s. Enjoy your new device!
