Apple's iPhone 4 pre-ordering has been plagued by all kinds of snafus, but now an AT&T insider claims the problems may be related to "a major fraud update that went wrong" that's exposing AT&T users' private information.

So far there have been at least three accounted cases of mistaken identities sent by readers of "Gizmodo.com" (http://gizmodo.com/5564262/apple-iphone-4-order-security-breach-exposes-...). The site says it happens this way:

"A customer tries to log into their AT&T account to order a new iPhone 4 upgrade. Despite entering their username and password, the AT&T system would take them to another user account. This gives access to all kinds of private information about the mistaken customer: Addresses, phone calls, and bills, along with the rest of private information, becomes exposed to random strangers."
