Apple releases iOS 5.0.1 update to fix iPhone 4S battery issues, available OTA as well
Apple has today released its iOS 5.0.1 update (build 9A405) to address battery issues, add multitouch gestures to the iPad 1 and more. The update is now available in iTunes, and is also available over-the-air to existing iOS 5 users.
Some users may not see the over-the-air update immediately, so either be patient or just use the iTunes update method. We recommend waiting and doing the update OTA because the update experience is much quicker this way, due to the smaller size of the update file (the iPad 2′s update is only 34.9MB OTA), and very slick.

The fixes that are listed are:

  • Fixes bugs affecting battery life
  • Adds Multitasking Gestures for original iPad
  • Resolves bugs with Documents in the Cloud
  • Improves voice recognition for Australian users using dictation

Apple has also included an explicit fix for the security issue discovered by security researcher Charlie Miller just a few days ago. In addition, there is a fix for the iPad Smart Cover security glitch, which would allow users access to your last running app.
To get the update now, plug your device into iTunes and click update, or if you’re already on iOS 5, you can go to
Settings>General>Software Update to update your device.

Impact: An attacker with a privileged network position may intercept user credentials or other sensitive information
Description: Two certificate authorities in the list of trusted root certificates have independently issued intermediate certificates to DigiCert Malaysia. DigiCert Malaysia has issued certificates with weak keys that it is unable to revoke. An attacker with a privileged network position could intercept user credentials or other sensitive information intended for a site with a certificate issued by DigiCert Malaysia. This issue is addressed by configuring default system trust settings so that DigiCert Malaysia’s certificates are not trusted. We would like to acknowledge Bruce Morton of Entrust, Inc. for reporting this issue.
