Apple will offer a sneak peek of iPhone OS 4 on 8 April, with analysts speculating that the company will finally bring multitasking to the software.

The Cupertino-based company has begun sending out invites to journalists and analysts to attend an event at its headquarters, and “Get a sneak peek into the future of iPhone OS.”

The event will take place at 10am Pacific time, or 6pm GMT.
The invites come hot on the heels of the iPad launch, and the rumour mill has already sprung into life on what new features lie in wait.
High on many people’s wishlist is multitasking, which will allow the iPhone to run multiple apps at once, and switch between them at will. While the current iPhone OS allows people to continue listening to music while they get on with something else, that’s about the extent of the functionality.
However, rumours suggest Apple plans to change this with a modified version of the Expose feature from Mac OS X.
Expose allows Mac users to quickly view all open windows, and select the one they want. According to reports, a similar option will be made available on the iPhone, with users able to browse icons of running apps.
It’s also been suggested that Apple plans to roll out a new mobile-advertising platform called iAd. It’s believed iAd will allow advertisers to serve location-aware advertising to users, and could possibly fuel a raft of free services and applications on the iPhone.
