When an SMS/text message arrives, the iPad shows a preview of it on the home screen. This feature, though convenient, might pose a security threat, particularly in a cloud-oriented world where corporate workers take mobile devices wherever they go. Say you're in intensive negotiations with a client, and you set your iPad on a conference table for everyone to see. BAM! A potentially damaging message pops on the screen -- "the client's mom wears army boots." Guess who reads it? Smartphones, including the iPhone, have a preview feature too, but their screens are smaller and easier to conceal. A full-size iPad, on the other hand, provides a tempting target for wandering eyes.
Good news: It's easy to turn off home screen preview. Go to Settings --> Notifications --> Show Preview, and slide the button to OFF. Remember, even if you're aware of this tip, your colleagues might not be. So spread the word.
