While Mac OS X 10.6.8 resolves numerous security vulnerabilities for Snow Leopard users, those still using Mac OS X 10.5 Leopard should download and install Security Update 2011-004. The most important fix is to AirPort, and it prevents an attacker on the same Wi-Fi network from causing your Mac to reboot. Other affected aspects of Mac OS X include ColorSync, CoreGraphics, ImageIO, MySQL, patch, Samba, servermgrd, and Subversion. Separate standalone updates are available for Leopard and Leopard Server, though it’s still easiest to let Software Update do its thing. (Free; 256.4 MB, 499.8 MB)
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.
