Apple has released iOS 5.0.1, which addresses the poor battery life experienced by some users under iOS 5. The update also adds some multitasking gestures to the original iPad and makes some security tweaks.

Among the latter is a Smart Cover exploit that allowed people to skip passcodes and gain limited access to an iPad 2. iOS 5.0.1 also addresses vulnerabilities in components such as DNS and URL handling, font handling, and weak certificates associated with DigiCert Malaysia. Apple also says that the update fixes problems with the file-syncing part of its iCloud service and improves voice recognition for Australian users of the iPhone 4S’s dictation feature.
