This research finding from Georgia Tech sounds like it comes from the plot of a high-tech thriller — a team has figured out how to listen in on what someone is typing on a nearby keyboard by using the accelerometer and gyroscope of an iPhone 4 to sense keyboard vibrations and decipher sentences with 80 percent accuracy. Although the actual risk of this happening is essentially non-existent, it’s yet another example of just how important it is that smartphone security be maintained by manufacturers and users alike. follow link
See All Your Books in iBooks
The iBooks app for iOS lets you assign your books to different collections, but does not have any obvious way for you to see all of your books, regardless of the collection you have put them in. There is, however, a workaround that can show you just about all of your books at once: reveal the search field at the top of any collection in iBooks and type a single space into that field.
With this search, iBooks lists all of the books that have a space either in the title of the book or in the author's name. Other than the rare book that has a one-word title and a single-name author, you end up with a list of all of your books.
