Ha Lol, she gets the latest phones every year anyway on iPhone tho if u want decent amount of storage u can pay big $$$! but that is prob what happened
Forgot to mention that she doesn't even know why she wanted an iPhone, nor does she particularly like it, but it's probably too soon to let out that secret.
Also, don't forget that no matter how much phone storage you'll get her, it will get full. The advantage of the iPhone is that it will automatically move photos to the cloud for storage (assuming you have that set up and are paying at least $0.99/month for that storage). It seems like the Pixel has something about unlimited Google Photos, does it help manage phone space?
