Apple sends out invitations for iPhone event on Oct. 4

NEW YORK, N.Y. - Apple is inviting journalists to its Cupertino, California, headquarters next week for an iPhone-related event on Oct. 4.

The invitation Apple Inc. sent on Tuesday does not go into details. It says "let's talk iPhone," suggesting that the usually secretive company is likely to unveil the next iteration of its popular smartphones.

Former Vice-President Al Gore, who sits on Apple's board, has said recently that he believes Apple's new iPhones will be here in October.

Next weeks' event will be the first product unveiling for Apple since Steve Jobs resigned as CEO in August. The company's shares have since hit their highest level ever.
