Apple released iOS 5.1.1 for iOS device owners today over-the-air and in iTunes. The update brings several bug fixes and improvements, including a fix for certain iPads that loose connectivity when switching between 2G and 3G networks.
An important security update has also been included in iOS 5.1.1 for a URL spoofing technique in Safari that made the news a couple weeks ago.
Apple has patched the vulnerability in the newly-released iOS 5.1.1:
Available for: iPhone 3GS, iPhone 4, iPhone 4S, iPod touch (3rd generation) and later, iPad, iPad 2
Impact: A maliciously crafted website may be able to spoof the address in the location bar
Description: A URL spoofing issue existed in Safari. This could be used in a malicious web site to direct the user to a spoofed site that visually appeared to be a legitimate domain. This issue is addressed through improved URL handling. This issue does not affect OS X systems.
iOS device owners can install 5.1.1 now to receive this security patch alongside two WebKit vulnerability fixes.
