Can I have different Apple IDs on my iPhone 4S? iCloud has an Apple ID:

Settings &gt; iCloud 


Messages has an Apple ID:

Settings &gt; Message &gt; Receive At


Store has an Apple ID:

Setting &gt; Store


Do these all have to be the same ID?  If not, which ones can be different?

Or to ask this question a different way... 

My wife and I both have a 4S.  Can we share the same ID for iCloud (calendar sync) and Store (app sync) but not for Messages (distinct text identity)?

TIA
Each place you mention is separate so you can use a unique Apple ID in each. Other than the App Store / Music Store where you can only enroll 10 devices in a 90 day period), you can use one account on many, many devices.

In addition, the iCloud account that is entered into iCloud does control Photo Stream, Documents and Backup for the entire device.

Your additional iCloud accounts can be entered into Mail, Contacts, Calendars to have additional:
