Apple is to improve security on iPhones by automatically disabling the data port one hour after the phone is locked. You can still charge the phone but won't be able to use the data port until unlocked by the user. This will be built into a future update, although not specified when.

But privacy advocates said Apple would be right to fix a security flaw that has become easier and cheaper to exploit. “This is a really big vulnerability in Apple’s phones,” said Matthew D. Green, a professor of cryptography at Johns Hopkins University. A Grayshift device sitting on a desk at a police station, he said, “could very easily leak out into the world.”
