You would have to go to icloud.com from your computer and manually delete all the data, then delete any backups from your account from your phone (Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device in the Backups list, tap Delete Backp). Or, you could create a new account by going to Settings>iCloud, tap Delete Acccount, choose Keep on My iPhone, set up the new account with a new ID, turn on your iCloud data syncing and choose Merge when prompted. You would, however, be leaving your existing iCloud email address behind.
