sync and iCloud
I brought home a new 6s and accidentally synced it up as my wife's account. How do I undo this and get it uploaded with my info, contacts, acts, etc?
iPhone 6s, iOS 9.1
Erase All Content and Settings.
Erase all content and settings on your iPhone, iPad, iPod touch, or Apple Watch - Apple Support
I hope this answers your question.
Best regards,
