iMessage and FaceTime account wrong After my recent software update my iMessage and FaceTime account changed to my husbands on my iPad.  How do I change it back to mine?
That is a very generic question to ask in this community. Please try following this tutorial http://osxdaily.com/2014/08/01/change-apple-id-ios/ to sign out of your husband's iCloud account completely (i.e. iCloud, iTunes etc), and be sure to sign in with your own.

If you remove his login information by logging him out and using your credentials instead, there shouldn't be any reason why the problem should persist.

Good Luck, let me know how you get on.
