Sources: Data from San Bernardino phone has helped in probe

In case you're wondering, the way accessing the data helped:

> The phone didn't contain evidence of contacts with other ISIS supporters or the use of encrypted communications during the period the FBI was concerned about. The FBI views that information as valuable to the probe, possibilities it couldn't discount without getting into the phone, the officials said.

If this is the threshold for gathering information, then there's no way the data could not have helped.
