Apple on Monday announced a special media event at it’s Cupertino, Calif. headquarters to give users a sneak peek at “the future of the iPhone OS.”

The invitation-only event will be held on April 8, 2010, the company said in the invitation sent to The Loop, from the company.

Clearly, iPhone OS 4 will be unveiled, but there is no word whether it will be for the iPhone, the iPad, or both.
