Removing iCloud on an old phone I have iCloud on more than one phone—my old iPhone 5c broke and the screen doesn't work. I now have a new phone with iCloud backed up and it works fine. I want to sell my old phone but they state that iCloud must be removed. How do I do this on icloud.com without wiping my other phone?
Connect your iPhone 5c with your PC/Mac and open iTunes
  Restore the 5c to factory settings (http://support.apple.com/kb/HT1414)
  Go to your Apple Support Profile and de-register it.
  


That should be it.

In addition, you can delete old iPhone Backups from the iCloud:


  
  Go to Settings > iCloud > Storage &amp; Backup > Manage Storage.
  Tap the name of an iOS device whose backup you don’t need, then tap Delete Backup.
