I have an iPhone and an iPad. My parents each have their own iPhone. All are using my apple ID. All 4 devices are also using said apple store account for icloud. I have MobileMe and will use that as my iCloud on my iphone and ipad when I can. Question is will I need to make my parents each their own iCloud account because they have different personal emails and contacts calendars etc. Also would it be possible to use that app store account across all 4 ONLY for purchases and no syncing.
