More IPhone 3G internals photos





Portelligent and Semiconductor Insights published a document describing interals of IPhone 3G. Techonline described the details. (Previous IPhone 3G internals photos can be viewed here)

Commuunications (3G/GSM) are on Infineon chips. One for GSM/GPRS/EDGE, another for WCDMA/HSDPA (3G). GPS module is not SiRF as we all thought. Apple uses PMB 2525 Hammerhead II. The Hammerhead II integrates an assisted-GPS (A-GPS) baseband processor with a low-noise GPS RF front end and multi-path mitigation to avoid large errors in urban environments.

Free vs paid IPhone applications by category



Pinchmedia recently announced new report regarding IPhone applications (take a look at the previous one here). They counted free and paid applications in each category. Guess what the results are:

News and social networking are disproportionately free, since it's difficult to charge for content that's freely available elsewhere and social networks grow in value with the number of participants. Entertainment and games are disproportionately paid, reflecting a belief that people will pay money to have fun. Since the AppStore's applications are disproportionately entertainment and games (helped along by a lot of $0.99 e-books), the AppStore's applications are predominantly paid. The most common price for an application in the 'games' category is still $9.99, although the second-most common price is $1.99.

IPhone application price



The Apple's online store with applications for IPhone is opened. Here are some statistics provided by pinchmedia. They counted 559 applications - 421 of them paid, 138 of them free (7:00 PM EDT). Paid applications ranged in price from $0.99 to $69.99, with the most common price points being $0.99 (85 applications), $9.99 (82 applications), and $4.99 (62 applications). A bar graph of iPhone application price distribution can be viewed in the beginnings of this post. Of course every day there are going to be more and more IPhone applications avaliable in iTunes store.

IPhone applications are in iTunes Store



Here are the news from Apple: "When the iPhone 3G goes on sale tomorrow, more than 500 native applications will be available on the revolutionary new App Store — including more than 125 free applications."

But the applications are already there!! Because in some parts of the world it is already July 11. And what is great, there are many free applications. For example, Remote, AIM, Google Mobile, NYTimes, Myspace Mobile.

Users can download applications directly from new IPhones or through iTunes.

New version of JocStrap and UICaboodle is avaliable



These two libraries that are needed for Java on IPhone were updated recently. Downloads are avaliable through Cydia Installer.

Jocstrap is a bridge between Java and Objective-C. UICaboodle is a JocStrap extenstion for the IPhone. Both are needed to write Java applications for IPhone.

Not only Java for now



Hello, everybody!

There were many visitors to Java4IPhone site recently. This is great! I like the idea, that this site is useful. Most visitors are from the US and Russia (since there are 2 languages supported). But I see quite a lot of interest from all over the world: Europe, China, India, even Kuwait and Maldives :)

So I decided to extend the site news to everything that is IPhone related. For those who is interested only in Java on the IPhone there is a category Java+IPhone with subcategory Java Applications.

Stay tuned and have fun.

JavaSysInfo - another sample GUI Java application



javasysinfo.png

This is another simple Java GUI application for the IPhone/IPod from Java Flavor Weblog. It simply shows Java system information on iPhone/iPod touch. It uses Java, JocStrap and GNU Classpath.

This application can be installed through Installer. Just add the repository http://javaflavor.cocolog-nifty.com/apptapp/. The application can be found in Java section and is called JavaSysInfo. Or just download it here: javasysinfo-092.zip. The package includes compiled class files, source java files and runnable script with an icon. Here are the sources: JavaSysInfo and JavaSysInfoController.

Note that JocStrap applications, including JavaSysInfo, currently require JocStrap, UICaboodle, JamVM, GNU Classpath, GNU Classpath Tools, Apache APR, libffi and BSD Subsystem. In most cases all this was installed during Java on IPhone installation.

IPhone's new patent application



patent.jpg

Apple recently filed a new patent application (us20080122796ki). On more than 370 pages lots of new potential features and enhancements for IPhone’s hardware and software are described.

The most interesting Hardware part is a GPS receiver and a camera for video conferencing.

On a software level, Apple describes addition of a text messaging (chat), in-line multimedia content (Quicktime and Flash) in the Safari browser. Further welcome additions described in the publication would include a dedicated blogging client, Java software downloads, MMS picture and video messaging, support for voice-activated commands, audio capture, video conferencing and more.

“[0142]Examples of other applications 136 that may be stored in memory 102 include other word processing applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication. ”

It sounds like Apple wants Java to be on the IPhone :-)

Cannot create? Convert!



There are two ways to enable Java applications run on the IPhone. The first one is to port Java to IPhone, and this is preferrable :) The second way is to create automatic Java to IPhone porting solution for individual applications.

A company called Innaworks announced an interesting product called alcheMo. alcheMo is an automated system to port J2ME application to a native platform such as BREW and IPhone.

alcheMo technology is basically J2ME to C++ translator and the run-time library. It converts Java application to C++ application, which can be compiled, run and debugged. Using native run-time libraries the native executable is created. The alcheMo run-time library provides equivalent functionality to those associated with J2ME, including support for automatic garbage collection, multi-threading and extensive subsets of CLDC 1.1 and MIDP 2.0, and extension JSRs.

alchemo_workflow_400x207.png

There are several examples of porting games to BREW platform. Hopefully there will be some for the IPhone in the near future. For now alcheMo is in beta state, potential developers are invited to join.

By the way, alcheMo for iPhone supports the accelerometer, the touch screen and other unique iPhone features, through standard MIDP 2.0 API, JSR-256, and, where necessary, extension APIs. If J2ME application uses such APIs, it will automatically and immediately be accelerometer or touch screen capable on iPhone.

To be or not to be?



java iphone

We are all waiting too see Java logo on our IPhones. I do too. But... there are obstacles and restrictions. The main point is that Sun really wants see Java on the IPhone. Community wants to see it. Large companies want to be able to create Java based applications. This is a huge market. However there will be probably no Java if Apple doesn't want it to be. That's what I've heard from a vice president of Sun Microsystems. The good news is that Sun wants to be ready with Java for the IPhone in case of everything will go well. So I assume there are investigations and probably some development going on already. And of ofcourse lawers are working hard too :-) .

So what about Apple? Apple will be able to make money with Java. There is a huge market and big money. Enterprise solutions, regular applications and etc. Everybody will benefit from it. We'll see quite soon, what will happen.

Official Sun Microsystems announcement



JavaEric Klein, vice president of Sun Microsystems, Java Marketing anounced that Sun will be developing a Java VM for the Apple's IPhone. This JVM will be based on Java Micro Edition and will allow IPhone to launch thousands of existing and new Java applications. "Once our JVM is on the phone, we anticipate that a large number of Java applications would run on the phone," Klein said. It took 24 hours for Sun to analyze the licence and information Apple had provided with IPhone's SDK. Release date is planned some time after June 2008.

Download the official recordings: audio - mp3 (335 kb), video - mp4 (4.9 mb).
