iOS 5.0.1 beta contains improvements and other bug fixes
- 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
- Contains security improvements
I can’t think of a good reason why the multitasking gestures weren’t enabled for the original iPad in 5.0.0.
