Facebook today released a much-anticipated update for iPhone that makes loading News Feed, photos, messages and notifications significantly faster.
Previously, Facebook built its mobile apps with HTML5, which allowed it to release daily updates without requiring users to download a new version. This helped the company test new things and scale the app to hundreds of millions of users. But the user experience suffered because the app was so slow. Now with version 5.0, consuming content in the feed, adding comments, checking messages and notifications, and other actions happen almost instantaneously.
