Two iOS apps, Twitterific and 1Password, have today received significant updates. Twitterific 5.2.2 adds support for bookmarking service Readability and image service Droplr. A number of smaller improvements have also been made, such as automatic flipping of the read/unread state of tweets as users scroll, and similar updating of indicators in timeline tabs. Yfrog images should appear in the in-app browser instead of the photo viewer.
