Made a reservation for two Silver 64gb using my Apple ID. Mom wants Rose Gold 64gb but there wasn't a way to reserve two different models in the same transaction. Tried reserving with her Apple ID and kept getting the "Upgrade Your Apple ID" error. Thanks for the tip and link to change her password, so now she's got two Rose Gold phones reserved at the same time slot as me. Figured I might as well take a look to see if I prefer Rose Gold over Silver (doubt it, but it's nice to have options!). Pretty smooth ordering process; hopefully the in-store process is as smooth.
