I want to get some developer to make a iphone app for my ecommerce business but not sure that do i need any hosting package(as like web hosting) as well. Someone told me that it will host via Apple server and i don't have to buy any hosting service. Please Help? Thanks in advance.
you already pay apple to publish / host / advertise your app. to what degres is a choice. so simple answer is NO you do not need seperate hosting for your iphone app. web hosting is only for your website/business and that's a different story altogether.
