Apple today released an updated version (v.1.2) of its MobileMe iDisk app (free, App Store) that supports the iPad and iOS 4.0.
The updated iDisk is a universal app, meaning that the same app can run on both the iPhone and the iPad. The killer feature is multitasking support when running iOS 4, which allows you to quickly switch to another app and back to iDisk. When you re-open the app the last file or directory you were viewing is displayed.
Other new features include the ability to play audio from your iDisk in the background while using another app and to open documents stored on your iDisk in compatible apps such as iBooks (PDFs) and Pages, Numbers and Keynote files in their associated apps.
Version 1.2 also allows you to email a file on your iDisk from any email account that's configured on your device where previously it had to come from your MobileMe account.
A nice upgrade all around.
