October 4th will be the Day of the iPhone for 2011.

Featuring a clandestine message that read "Let's Talk iPhone," Apple's invitations state that the event will be held at Cupertino's home campus on October 4th at 10AM PST.

The announcement is most certainly the unveiling of the long awaited iPhone 5 and iPhone 4S, but we will only know for certain on October 4th.

TechnoBuffalo will be live blogging the event, so be sure to tune that dial to the Buffalo at 10AM PST/ 1PM EST on October 4th.

Did we mention Apple will be revealing its new iPhone(s) on October 4th at 10AM PST?
