After the news about Apple's lawsuit many of us have been wondering why Apple did this. Obviously, the thing is not about money as the company already has $40 billion of cash and investments. Digital Daily's editor John Paczkowski thinks the reason is a desire to extend iPhone's growing lead on the market.

"Apple is suing to make an example out of HTC and lengthen the engineering time-to-market for Android handset builders."

While other Android smartphone manufacturers will spend their time solving a problem with developing of noninfringing technologies to avoid lawsuits, Apple will continue to iterate the iPhone.

Ok, this is clear, but why Apple accused HTC now?

The Unreal Engine 3 is a modern 3D gaming engine which powers games such as Bioshock, Gears of War and Unreal Tournament 3.

Anandtech spent some time with Mark Rein (Epic Games) last week and was shown a demo of the Unreal Engine 3 running on a 3rd Generation iPod Touch. The demo included a flythrough as well as a playable level from Unreal Tournament.

The game engine requires OpenGL 2.0 so this will restrict the game to 3rd generation iPod Touches and iPhone 3GSs only. Epic is planning on making the engine available to licensees at some point, opening the door eventually to Unreal-powered iPhone games. Epic tells Anand we're going to see Unreal running on another mobile platform at CES.

Let's watch the video demo:

We published several news about new firmware 4.0 and even new iPhone 4 hardware. Recently one more iPhone developer has noted a single instance of iPhone OS 4.0 being used in their Pinch Media analytics. While such data can still be faked, it seems less likely to be. Testing of iPhone OS 4.0 may correspond with reports of new iPhone hardware also being tested. Any new iPhone would require a new version of the iPhone operating system to support the new hardware.

We can not yet imagine the features of this new OS or the new device. Apple is widely expected to release a new iPhone in the summer around WWDC 2010.

It seems Apple is continuing to invest in advancing web-based technologies to provide a more full feature experienced on the iPhone and iPod Touch. Daring Fireball describes in detail an impressive new web framework called PastryKit. This kit is for making HTML, CSS, and JavaScript-based WebApps.
It is already deployed in Apple's iPhone User Guide web page (when viewed from an iPhone). You can watch the video at hte end of this post.

Apple has implemented a few key interface features in Javascript that could make web-apps feel much more like native iPhone apps. These include:

• Completely hiding the address bar
• Allowing for fixed-position toolbars that don't move when you scroll
• Allows for scrolling with momentum so you can quickly scroll long lists

Since these features have been implemented by Apple in Javascript, they could be available to any web developer.

Let's watch the video:

MacWorld performed several tests between all the Apple devices: iPhone 2G, iPhone 3G, iPhone 3GS, iPod Touch, iPod Touch 2G, iPod Touch 3G. Here are the results, all in one table:

Results are in seconds. Best results in bold. All devices were tested running iPhone OS 3.1. Peggle and Star Defense were app launch times to end of initial load screen. PCalc was launch time to calculator ready. Sunspider was the time to run the WebKit Sunspider JavaScript benchmark. Page load test was amount of time it took to load nytimes.com.

A few days ago we reported that the statistics showed an increase in speed of firmware 3.0 compared to 2.2.1. This factor, however, does not find confirmation in other applications, because, as you can see from the following table that 3.0 is slower than 2.2.1.

For example is takes 34 seconds to start for firmware 2.2.1 against 47 seconds for 3.0 firmware. The launch time of some applications on the old firmware also sees an advantage of 2-9 seconds compared to 3.0. This is just further evidence showing that the 3.0 firmware has problems and should be optimized. We hope that the update arrives soon!

Medialets today released the results of JavaScript benchmark tests performed using the SunSpider test suite on the iPhone 3G and 3GS, the T-Mobile G1 running Android, and the Palm Pre running webOS. The use of the SunSpider suite for benchmarking studies enables cross-platform comparisons among the devices, as they all utilize WebKit-based Web browsers. In the Medialets study, the iPhone 3GS outperformed the Palm Pre by a factor of three and the T-Mobile G1 by over a factor of five.

Notably, Medialets also tested the iPhone 3G running both iPhone OS 2.2.1 and OS 3.0, revealing that iPhone OS 3.0 provides a nearly three-fold improvement in performance over OS 2.2.1 running on the same hardware. The shift to the iPhone 3GS increases performance a further three-fold.

NimbleKit a good kit that will help to create an application for iPhone. Developers can use just HTML and JavaScript, there is no need in any special knowledge relating to Objective-C.

There is application fee, but you can download a trial version directly from the official site. Below is a video with the first tutorial that shows how to create an Internet Radio:

While still in beta, the Firmware 3.0 includes a new version of Safari that integrates the latest WebKit. It uses SquirrelFish Extreme ("Nitro") as an engine for JavaScript. The benchmarkes shows that the new firmware is 3 to 10 times faster, depending on the type of action.

Now iPhone users can search in Safari browser. This is one of the features I was waiting for a long time.

Here is what you need to do: open Safari and go to http://www.ipuhelin.com/en/safariplus/, click Find in page and follow the instructions which are:

One more solution for CopyPaste functionality using javascript and bookmarks.

Qik has released its mobile video streaming application for jailbroken iPhones to the public. The service allows users to broadcast video live from their phones using Wi-Fi or the EDGE network which can be viewed on Qik’s site or through its embeddable player. Unfortunately, the application is only compatible with phones running the 1.1.4 firmware.

Users running the 2.0 version of the software will need to wait for Qik to release a compatible version, which the company expects to do in the near future. Unfortunately, it’s likely that the application won’t be available through the official App Store, as Apple still hasn’t enabled video capture using the phone’s integrated camera.
