Well the wait is over – iPhone 4 Jailbreak is out!.

Comex and other members of the iphone Dev-Team have released the newest iDevice Jailbreak.

JailbreakMe 2.0 Star is the name! – The userland jailbreak for iPhone 4, iPhone 3GS, 3G on iOS 4 / 4.0.1, iPod touch on iOS 4, and iPad on iOS 3.2.1 is out !!. It is a browser based jailbreak, all you have to do is to browse to http://jailbreakme.com from your iOS device to jailbreak it.

Yes you read that right, no need to plug your device in to a computer, go ahead and jailbreak your phone while you wait in line at Starbucks!

Once the process completes (took about 3 minutes on my 15mbps wifi connection at home) you will have Cydia on your homescreen all ready to install your favorite jailbreak apps!

There is one warning floating around right now and that is to update your iPhone 4 to iOS 4.01 before jailbreaking to avoid Facetime and MMS issues.  And to play it extra safe, restore your iphone from a backup in itunes once you have finished the jailbreak.

Here is a full list of supported devices:

iPod 1G on 3.1.2
iPod 1G on 3.1.3
iPod 2G on 3.1.2
iPod 2G on 3.1.3
iPod 2G on 4.0
iPod 3G on 3.1.2
iPod 3G on 3.1.3

Step by Step Instructions:

Step 1: Start iTunes and backup everything from Contacts, Calendars, Photos, Videos and Apps.

Step 2: Update your iPhone 4, 3GS or iPhone 3G on the latest iOS 4.0.1 firmware with iTunes. Download links for the firmware and iTunes 9.2.1 can be found below.

Step 3: Once you are done with the update, make sure you are connected to a WiFi network. I haven’t tested it on 3G so I recommend using it on a reliable WiFi network.

Step 4: Open Safari on your iPhone 4, 3GS or 3G and navigate to http://jailbreakme.com.

Step 5: “Slide to Jailbreak” to begin the jailbreak process.

Step 6: Wait till the jailbreak tool download the required files.

Step 7: Once the download is completed, it will automatically start the jailbreak process. Just don’t do anything silly at this point. Wait till the jailbreak process is completed.

Step 8: Once done, you will be greeted with the following message: Cydia has been added to your home screen. Have fun!

Step 9: Close the browser and look for Cydia. You should now have it on your phone!

    Windows 7 Maintenance Tools Part 2 – Disk Defragmenter

    The Disk Defragmenter at Work

    Another valuable tool to keep your computer running efficiently and smoothly is Disk Defragmenter. This tool tidies up fragmented files on your hard disk drive.

    What are Fragmented Files?

    As your hard drive gradually fills up with stored files, there comes a time when you need to delete redundant files to make more room. This leaves empty spaces from the deleted files scattered over the disk.

    So, when you download a large file, or install more software, there may not be enough room in any single space on the disk to fit the entire file. Windows has no choice but to store the file fragments in several places. This makes for a fragmented file.

    The more fragmented the files are on a drive, the more your computer’s performance and reliability suffers as the hard drive has its work cut out searching for these scattered pieces files. Hence it is slow loading your data.

    Terminology
    • A large file with the scattered parts is called a non-contiguous file.
    • A file, not broken up into pieces, is called a contiguous file. System files are always contiguous. They should never be deleted or moved as they are necessary for the system operations.

    Windows Defragmenter in Earlier Versions of Windows

    In the earlier versions of Windows, the Disk Defragmenter was a vital tool. When you ran it, Windows displayed a graphic image of a fragmented drive showing the before and the after.

    In Windows 7, the graphic display previously seen in the earlier versions of Windows is no longer visible. Instead, all the action happens behind the scene so you miss out on the graphics.

    In 2006, Microsoft released Windows Vista. It was supposed to be great but it was delivered years late, and when it finally released it was a slow, buggy mess that no one wanted to use. It wanted all of your memory, and it wouldn’t run well on the computer you already had without significant upgrades. People went out of their way to use its predecessor, since it was consistently faster and more compatible with their applications.

    Let me type that paragraph again, with a few subtle changes: In 2001, Apple released Mac OS X 10.0. It was supposed to be great but it was delivered years late, and when it finally released it was a slow, buggy mess that no one wanted to use. It wanted all of your memory, and it wouldn’t run well on the computer you already had without significant upgrades. People went out of their way to use its predecessor, since it was consistently faster and more compatible with their applications.

    Microsoft’s advertising campaign has already raised a few eyebrows with its “odd” videos and launch parties. Now Microsoft’s Hong Kong Subsidiary has decided to take a new approach for its marketing campaign by launching a Windows 7 Personality Quiz.

    windows7quiz

    The quiz composes of 13 different questions which ask you things like ” Whats the most important thing to you when buying a computer” and “How many computer/laptops/netbooks do you own”. At the end of the quiz you will be told your personality, and of course Microsoft have found a way to link Windows 7 into it as well.

    How To Setup a Virtual PC Console in Windows 7

    Virtual Machine Technology is like having a computer inside a computer. It allows you to work with applications, create networks, write code in the .NET environment, trouble shoot applications, all in a sandbox environment.  Here the virtual machine and its operations are kept separate from the core-host machine. If the virtual machine blows up, the host machine is unphased.

    Virtual Machine technology allows businesses to have multiple servers on one main server. Suppose a company needed to have a mail-exchange server, a database server running Oracle, and another running Sql server 2005, another server running financial software and one or two servers running manufacturing and engineering software. This could get very expensive. The company would have to purchase the hardware and the software. But by having a virtual machine environment, instead of having to purchase 4 or 5 computer-servers, each costing between 7 and 10 thousand dollars, a company only needs to buy one. That server would be loaded up with RAM and Multi-Core processors to handle the operations of several different virtual machines. Indeed the server may well cost upwards of 15,000 dollars. Still this would be a lot less than spending 40 to 60 thousand dollars on hardware. Now, the company only needs to buy one server, and the software to run on each virtual machine.

    This is the way of the future and Windows 7 offers an opportunity to do this.
    Once you have Windows 7 in place,  Download the Virtual PC  2007 Progarm from Microsoft. Read the rest of this entry »
