Not so long ago the iPhone 3G was released and the rumor mill is already churning out speculation about an upcoming iPhone 4G, expected as early as May. For months, and more in recent weeks, rumors have been buzzing with rumors about the Apple iPhone next generation 4G.

We learn that the new iPhone 4G must have:

Touchscreen OLED
Removable
Dual Core
Video Calling
5 megapixel camera (HD video recording and flash LED is also likely)
Double storage capacity (64GB and 32GB)
So yes, the new iPhone would be a big step forward compared to the iPhone 3G today. But it seems that Apple does not stop there.

In the light of Robert Chen (a Goldman Sachs analyst), 4G Apple iPhone launched in Jun, but will feature something never seen before in the mobile world, even in high-end smartphones.

Apple will also incorporate a number of innovation not only in hardware but also software aspects.

They said, the iPhone 4G next generation will have a touch-sensitive outer envelope as the Magic Mouse from Apple. What is the idea behind it? This may be easier for the functioning of the interface and enables more complex operations. Something like the Microsoft Surface concept shown several years ago.

Nothing is certain yet. But we hope, the rumors are true and the next iPhone revolutionizes the mobile industry.

Apple made its application in a complaint filed with the International Trade Commission, an independent federal agency that addresses issues such as unfair trade practices regarding patent, trademark and infringement of copyright.

In Dec, Nokia filed its own complaint with the International Trade Commission in Washington. In it, the Finnish company claims that Apple infringes seven Nokia patents “in almost all of its mobile phones, portable music players, and computers” and tried to ban imports of Apple’s iPhone, iPod, and MacBook products.

The ongoing patent battle between Apple and Nokia escalated Friday, when Apple moved to block imports of Nokia cell phones to the USA.

In responding to Apple’s latest move, Nokia spokesman Mark Durrant told Bloomberg that “Nokia will examine the complaint when it is received and continue to defend itself vigorously. However, this does not alter the fact that Apple has failed to agree appropriate terms for using Nokia technology and has been seeking a free ride on Nokia’s innovation since it shipped the first iPhone in 2007.”

Apple has not yet responded to a request for comment on the presentation.

In October, before the patent debate between the two companies moved to the trade commission, Nokia sued in U.S. District Court Delaware involving 10 patents related to wireless devices, which Nokia said Apple has refused to license. Every iPhone model since the original, introduced in 2007, infringes on those patents, Nokia has charged.

The 10 patents it accuses Apple of violating are related to making phones able to run on GSM, 3G, and Wi-Fi networks. They include patents for wireless data, voice encryption, security and encryption, according to Nokia.

Apple then filed a countersuit accusing then copy the technology of Nokia within the iPhone. Apple said Nokia is violating a number of patents, from real-time signal processing methods to list scrolling and document translation, scaling, and rotation on a touch screen display.

In Nov, research firm Strategy Analytics reported that Apple had exceeded the quarterly results of Nokia mobile phones, bringing in $1.6 billion from the iPhone, compared with Nokia’s $1.1 billion in cell phone profits.

Head of new phones from Nokia, Rick Simonson, acknowledged in an interview earlier this month that 2009 had been a difficult year for the company. “Yes, we have lost ground in the smartphone space over the past 18 months, but the decline has stopped and stablized in the second and third quarters of 2009,” in the India Times, Simonson told.

“The new year will see [our] recovery in smartphones with the introduction of Maemo and the stabilization of the Symbian operating system, which by the way, continues to be the platform for the greatest number of smartphones, worldwide,” Simonson said.
