Apple has updated iTunes U to version 2.0, with a bunch of new features for students and teachers. Students in private courses can now pose questions on the course, any post, or an assignment; and students in the same class can join the discussion to ask questions or provide answers. Teachers now have the option of creating or updating courses from their iPads and can use the iWork apps to create course materials. Students and teachers both can now receive push notifications for discussions. follow link
Move to Top Shortcut in iPhone
On an iPhone, flicking all the way back up to the top of a long Web page can be a real drag. Instead, a single tap on the status bar moves you to the top of a page. (The status bar is where the clock is.) This tip also works in other apps, like Mail, Contacts, etc.
