My wife will be getting her own iCloud account for her iPhone, but there are many iCloud things that I would like to be able to share with her (at least sometimes). Is it possible to share any of the following? (possibly by linking multiple iCloud accounts to a single device or switching between iCloud accounts on a device, etc)
3rd party iCloud data
Calendar
Photostream
Contacts
