According to Toni Sacconaghi – analyst at Bernstein Research – there are about 1 million iPhones that were sold and are not being used with the AT&T network, which means that they were unlockedand 27% of the iPhones in the world don’t have a relationship with AT&T. Poor AT&T.

Taking in consideration that AT&T made a big contract with Apple to get the exclusive phone deal, these studies are definitely bad news for both parties involved. In the end, people that don’t stay with AT&T after buying the iPhone, aren’t making carrier payments, which results in a big loss for Apple.

Here are some numbers, so you can have an idea about the amount of money we are talking about:

If Apple hit its sales goal of 10 million iPhones by the end of fiscal 2008 but 30 percent of those don’t result in any carrier payments, its revenue and profit would be $500 million and 37 cents per share lower than expected.
