The move could make it impossible for Google employees to test iPhone apps and use certain internal apps. The move was first reported by The Verge. > A Google spokesperson said, "We're working with Apple to fix a temporary disruption to some of our corporate iOS apps, which we expect will be resolved soon." Apple did not return a request for comment.
