Apple recently sent out a notice to several media outlets yesterday telling everyone and their mother that they’re holding a new event.  What exactly’s in this event?  iPhone OS 4.0.  That’s what.

It’s no secret that iPhone OS 4.0 will bring major software enhancements to their landmark devices — the iPhone, the iPod touch, and of course, the recently released iPad.  But what will it bring exactly?  Only Apple can tell us. 

Will we finally get the multitasking features other smartphones already have, will Apple incorporate their recent aqusition of online music streaming service LaLa?  What about simply unlocking the FM radio already included in both the iPhone and iPod touch.  (Perhaps even the iPad?)  Time can only tell.  Be looking out on popular blog sites such as Engadget come April 8th.
