Verizon subscribers aren't the only ones who have been experiencing data leaks with the iPhone 5, notes the New York Times and 9to5Mac. The Times writes that the issue may be affecting AT&T and Sprint customers as well. 9to5 goes into detail about the AT&T side; one person complains that he's already accrued over $100 in overage fees, while another says that they managed to consume 2GB of cellular data in three days.
