They released a dedicated iOS app on the same month the App Store launched (July 2008), about a year after the first iPhone was launched. They had m.facebook.com (dedicated mobile site) in time for the iPhone launch (Remember when Steve Jobs said web apps were the future? I remember!) Messenger as a standalone app was released in 2011. They bought Instagram pretty much within two years of birth. The UX of a lot of the mobile products might not have been good - I don’t remember - but all things considered I would say they moved fast on mobile, at both the engineering and strategic levels, and it paid dividends.
