With the latest announcement of iPad, what came along is the iPhone’s new SDK 3.2.

Other than featuring iPad only split views and pop overs shown extensively during the Steve’s presentation, there are many more elements which look really interesting and would be very worthy for business and student oriented apps.

I am listing a few of them below:

1. File and Documents Sharing

The 3.2 SDK ads support for File sharing. Before 3.2 we could save the files only in the documents folder of the app, but now app will have access to a shared directory at following path:

Documents/Shared directory

Other important things to notice are:

When we plug the device into the computer, the directory will get mounted on the OS, and Windows users would be able to access the directory from My Computer, while Mac and linux users would see an icon on their desktop.

Users would be able to copy, delete and drag files into this folder.

2. Document Support

What this means is that now an, app can specify what all types of documents it can support, and whenever user tries to open a document of that type, this app would get launched.

3. Document Interaction Controller

Document Interaction Controller would let the user choose the app he would like to use to open a document, which is not associated with any app. It will also let the user preview the document before actually opening it.

4. Downloading files from internet and email attachments

The new OS would let the user download any type of file from the internet and open it with an app of his choice. This gives iPhone OS a more “complete OS” kind of feel.

5. PDF Generation

iPad is surely a great eBook reader and here comes the functionality which would add even more to the core. Now, iPhone SDK provides PDF generation APIs to the developers and this API would also let the app save the PDF file in shared folder.

What type of app, strikes me with that? Microsoft OneNote!!! Voila, developers can use this feature to develop a OneNote kind of app for students, where in they can take notes on lecture slides during the class and later export it to pdf for studying later on.

The possibilities are endless!!!

Even though, these features would surely take iPhone OS to next level, it still is missing one very important feature. Yes you guessed it right, Multitasking. iPhone 4.0, brings us the charm of listening to Pandora while working with iWork or reading with iBooks on iPad.
