Flipboard has released an update to its popular iPad content aggregation app adding iOS 5 support and customizable font sizes. Flipboard 1.5.3 now allows users to choose normal, large or extra-large fonts for reading articles, captions and comments. The update also adds native iOS 5 Twitter integration allowing users to use their iOS configured Twitter accounts to sign in without having to re-enter a username and password within the app. The latest version also addresses several other bugs and improves general iOS 5 compatibility, including a fix for an issue that caused Flipboard to take up an abnormal amount of space on the iPad for some users. Flipboard 1.5.3 is available from the App Store as a free download.
