Precise: anyone with access to the computers you have "trusted" to pair with your iPhone, can extract encrypted data from your iPhone because that's what the trusted pairing is intended to do.
There are also "backdoor" systems that Apple Store employees use to unlock your phones, which can be exploited by Law Enforcement to extract text messages, contact lists and photos.
Noting of course that Law Enforcement already has access to numbers you have called and all SMS & MMS messages you have sent by subpoena to the carrier responsible for your service.
