Firmware 2.1





Apple is already providing developers with a new iPhone firmware beta with enhanced location-finding that could lead to true navigation as well as the roots for background push services.

The one of new features is update to core Location - it can now recognize the cardinal direction of an iPhone with GPS as well as its velocity, both of which are ingredients necessary to providing turn-by-turn directions. The additions confirm statements recently by Apple's Greg Joswiak, who rejected earlier claims that iPhone 3G's GPS antenna wasn't powerful enough to handle navigation and in turn explained that "complicated issues" are holding the device back from serving as a true navigation unit.

Apple is also implementing a rough version of its background push notification service in the 2.1 firmware. Announced at the Worldwide Developers Conference, the feature lets third-party native programs receive data such as alerts or new messages without actively running. The measure saves processing power without interrupting some apps that depend on constant access to the Internet.

The inclusion of this early version of the code alludes to the 2.1 update becoming public at the same time as the push notification service itself, which is tentatively due for September. In the meantime, Apple and its US partner AT&T are known to be testing iPhone 2.0.1, a maintenance release that likely fixes some of the outstanding bugs with the initial 2.0 release.

xpwn 0.3 sources are now up



The development sources for xpwn 0.3, the firmware 2.0 version of our cross-platform jailbreaking library/command-line utility have been pushed onto github. DevTeam tested it on Linux, Windows XP, and Windows Vista for both the iPhone 2G and iPhone 3G thus far, but since it uses the same FirmwareBundles files as PwnageTool, and we know those work for the iPod touch, there ought not be any problems.

Being a suite of command-line utilities, this release is meant primarily for developers. While you can certainly jailbreak (both 3G and first-gen) and unlock (first-gen) with it, it's not really something you want to try without reading the lengthy, detailed README. If you don't have the patience to do that, this release is not for you.

For users this news mean that quite soon there will be a new version of winpwn, supporting 2.0.

Java GUI on IPhone (example)



During Java instalation there was sample programm installed. It is called HelloJava. It is a bit more complicated than basic console HelloWorld-type application, that we tried to compile and run during this tutorial. HelloJava uses gui and SQLite. It uses several classes, that are bridges to IPhone's functionality (GUI, sound, SQL, etc). But all that it does is it reads contacts' first and last names from IPhone's database (throught SQL select statement) and shows them on the screen in GUI mode. It also produses simple sound in the end.

Here is a screenshot of the icon and application itself:

The application consists of several files:

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.

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.
