Apple just released a new video advertisement for its much-awaited product iPhone. So what? Well, we managed to notice something a bit different on the mobile phone's interface, possibly hinting at a yet-to-be-unveiled function.

As you've seen from all previous iPhone images, the screen has 11 different icons -  two rows with four icons and the last one with just three. To make this easier, the last row is comprised of functions Calculator, Notes, and Settings. However, the video ad revealed the last row having four different icons.

Furthermore, all above-mentioned features were still there with the addition of the Clock feature. Those who have been anticipating this product for so long know well that the Clock function is positioned on the third row. This means, folks, that another icon somewhere at the top pushed it to the last row.

Sadly, the mysterious function wasn't shown in the ad at all. Is this a slipped up or a subliminal tease from Apple? Well, we will find out when iPhone finally hit retail stores later this month. The Read link will take you to Apple's page where you can view the ad in question.
