It appears that Apple did fix a “Find My iPhone” password issue that did allow unlimited password attempts to iCloud.

Yes, they did fix a flaw. . . But it turns out it was coincidental. The celebrities accounts were compromised by the simple means of the hacker going into “I forgot my password” and guessing the answers to their simple security questions and changing their passwords. Everyone of them had their passwords altered. They used things like “What car do you drive?” And “ In what town were you born?” Both questions for which the answers are easy to learn for celebrities. Dumb.
