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
Beware Country-Specific iTunes Stores
If you buy an iPhone, iPod touch, or iPad, and you happen to be a user of the iTunes Store in more than one country, take note which country's store you're viewing in iTunes when you plug in the device for the first time. This will be the country the device will register with, and you will be forever barred from purchasing or even updating free apps from anywhere else. The only way out is to delete everything on the device and do a full restore.
