Does everyone in a T-Mobile family plan have to have an iphone or can just 1?

I heard that somewhere (maybe about at&t? I don't know) and i'm wondering if family plans need to all have iphones or they won't let you use an iphone on their network. Please help i want an iphone but everyone else on my plan has androids?

Nope your fine, the early iphones were not comparable with the t-mobile network. Don't be afraid to call t-mobile customer service to ask all your questions. Cheers.
