This brings the string more in-line with the default User-Agent used to request the Mobile version of the site. The User-Agent string sent in this case remains the same, matching the Mobile Safari user agent, with CriOS/<ChromeRevision> instead of Version/<VersionNum>.
Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1
The goal of this change is to allow developers to tailor the user experiences to account for differences between Chrome and Safari on iOS. This change adds more information to the Desktop User-Agent string, but including the browser name and major version in the User Agent header is still in line with the goals of Chrome’s User Agent information reduction plans.
