After clamming up for months about the release of the most anticipated smartphone - iPhone 5 - this year, Apple has finally decided to sing. But it's not singing aloud - with a three word cryptic invitation, “Let’s talk iPhone” send out to the media, Apple has indicated that it will announce the launch of iPhone 5 on Oct. 4. And, nothing more.

The event will take place at the Apple campus in Cupertino, California and will begin at 10am US Pacific time.

Previously, there had been reports saying that Apple would launch iPhone 5 on October 4. Apple's invite gives us a good reason to believe other rumors that claim the new iPhone will begin selling from Oct. 14.

According to a Japanese website Macotakara, the 'iPhone 5' will release in the US, UK, France, Germany and Japan on October 14, ten days after the smartphone's likely unveiling. The site may be right given that Apple has stopped its employees from taking leave on Oct. 14 and Oct. 15.

In addition, Stephane Richard, the CEO of Orange France, has suggested Oct. 15 as the possible iPhone 5 release date.

Speculations about the new iPhone’s features have been like flyers, flooding into the Internet. The most popular rumors include an edge-to-edge bigger screen, at least in proportion to the rest of the body.

The new iPhone is also likely to possess an 8MP camera, an A5 dual-core processor, possibly a 1GB RAM memory and also will include the iCloud service.

However, do not let the excitement cloud your mind. There are some features iPhone 5 may be launched without. They are:

1. 4.3 inches screen

Apple is likely to enlarge its iPhone’s screen but probably just to 4-inches. Most high-end Android smartphone now have 4.3-inch screen.

2. Battery

Although iPhone 4 has an amazingly long battery life, it is unchangeable as it is a built-in battery. it is unlikely that iPhone 5 will have come with a changeable battery.

3.Flash

Adobe’s Flash player ?? amongst the mο?t widely used applications fοr one's online audio and video needs. Many Android smartphones support Flash Player but from the beginning, iPhone has mysteriously excluded support for Adobe Flash player. And, with Apple not showing willingness to cooperate with Adobe any time in the near future, it is very likely that iPhone 5 will not have Flash Player, either.

4. 3D

In the current market some smartphones have 3D display, such as the HTC EVO 3D. However, it seems that iPhone 5 will not have this function. In most cases, 3D display works better in a larger screen. Therefore, it can perform well in iPad but will have to be suitable for iPhone 5.

5. Over-the-Air Update

Over-the-Air update has become an increasingly important update and service function. The new mobile operating system iOS 5 includes over-the-air update function but Apple may not launch this function together with iPhone 5. At present, the Android devices download the updates over the air.
