@chpwn is a known hacker in the jailbreak community and always has been known for releasing some amazing jailbreak tweaks. Most of them are free and some are paid which are available in Cydia Store. Along with Ryan Petrich, Grant Paul have released Spire, a new tool for installing Siri on unsupported devices.
Spire is available for free in Cydia Store and it downloads the Siri directly from Apple, it is a huge 100MB file.
Despite all the efforts, Spire still has one small hurdle to clear, Authorization. Just like the previous tweaks and hacks, Apple still requires authorization to use Siri, so to send and receive information a iPhone 4S is still required. But to bypass that Spire allows you to add a proxy server which would help Siri function as it should via the Proxy server.

Paul has also setup a Spire Proxy FAQ to make it easy for anyone to get Siri working for their device.

All these efforts by various developers has finally paid off and now every jailbroken device could install Siri’s twin sister ‘H1Siri‘ via Cydia. The App claims to work exactly like Siri and all the requests are processed through a proxy server.

It is available on the this Cydia repository http://www.iphone3gsystem.fr/cydia/
It works as it is says but since it runs all the processes through a proxy server setup by the developers at CD-Dev Team it isn’t really advisable for you to install it as it might collect your personal data easily. Check the non-working demo by iDownloadblog.com after the jump.

Many known jailbreak developers have said that this hack works but is illegal and uses copyrighted binaries from the iPhone 4S .
Right now the proxy server is completely slammed and since the Siri requests were pouring is heavily the server is down and could be down for few weeks.

This might not be the perfect Siri port or a very legit way to port Siri to other devices, but surely the work done by the developers is commendable. The Cydia hack despite not being liked for its illegality it surely is the first fully working Siri hack and leaves us hopes of getting Siri on all devices soon.

Genius developers at Applidium have managed to decipher Siri’s security protocol and explained it on their blog very neatly. For users who might feel that blog post is very technical here what it means to you. If you don’t have an iPhone 4S, you can still get Siri on your device. Just wait for a developer to develop an App around the tools provided by Applidium.

There is only one problem in this, to communicate with Apple’s servers from another device you will need an identifier of iPhone 4S, as Siri requires the unique identifier every time it contacts Apple’s server, which is unique to each iPhone 4S. Without that identifier a device cannot contact Siri’s server and access would be denied. The developers haven’t revealed or released the unique identifier of their device, as there are chances that if Apple servers get too many requests from a single identifier it would be obvious that the identifier is being used by more than one device and it might get blacklisted or banned.

If you are a developer, you can read Applidium’s full technical post and use their collection of tools to easily decipher Siri’s security protocols and develop an App for some other platform or just to port it to any other iDevice.

This is actually the source code for version 4.0.1 of Android, which is the specific version that will ship on the Galaxy Nexus, the first Android 4.0 device. In the source tree, you will find a device build target named “full_maguro” that you can use to build a system image for Galaxy Nexus. Build configurations for other devices will come later.

Android 4.0 Ice Cream sandwich is designed to run on tablets as well as smartphones thus it becomes a successor to Honeycomb OS which was designed specially for tablets as well as big update for Gingerbread ( the earlier smartphone Android version )

Honeycomb’s source code was never released to public so this would be Google’s first open source tablet OS.

Check Android Open Source Project for more details.

It is mostly faced by jailbroken users but can be faced by normal users too.
Don’t worry there is a solution for that,This problem is not really from your side but this problem is due to a bug in Cydia’s back end because of which you get that error.
Cydia’s SHSH caching server saves your SHSH blobs to keep your safe and secure so you could downgrade later if you want.

This should get fixed soon anyways here is the solution for you.

• Download TinyUmbrella
• Launch it.
• Click on the “Advanced” tab.
• Uncheck “Set Hosts to Cydia on Exit”
• Click on “Apply Changes”
• Reboot your PC/Mac.
• Now Connect your iDevice to the computer and hold the Shift Key and Click on Restore in iTunes and browse for the IPSW file you downloaded.

If you are a non-jailbreak user or If this doesn’t help then try another solution

• Exit iTunes
• Locate your hosts file:
  • In Mac OS X /etc/hosts
  • In Windows c:\windows\system32\drivers\etc\hosts
• Open the hosts file with Administrator privileges using Notepad.
• Add the following lines to the very bottom of the hosts file:
• 74.208.105.171 gs.apple.com
• Connect your device to the computer
• Launch iTunes
• Put device into DFU Mode by turning your device off and then holding down the sleep and power button for 10 seconds, then release the power button but hold onto the home button until iTunes tells you that the device is now in recover mode
• Use the iTunes Restore feature as usual with the iOS device

If you want you can remove the “74.208.105.171 gs.apple.com” line from your hosts file again so that iTunes can properly update as usual.

As of now the site is up and running for European users only and they started just with HTC Sensation. You need to accept the terms and conditions and hereby sign to void your warranty if you use this tool. This means HTC would charge you for repairs if needed within the said warranty period.

Once logged in, the site would walk your through the entire process and for Android enthusiasts this should be really easy to follow.
Caution : Make sure you go through the whole process thoroughly before actually using the tool.

This has to be a very lucky day for Android developers and enthusiasts, first Google acquires Motorola Mobility and now HTC actually moving ahead with the unlock bootloader tool which was announced months ago.

So head over to HTCDev.com to get started!!!

As of now the stable build is Firefox 5, Firefox 6 is in the Beta build, Aurora runs Firefox 7 and shiny new Firefox 8 is in the nightly build. If you are clueless about all these builds, head over here to understand all the different Firefox builds which are available for everyone to try.

Check out all the UI-mockups at the Firefox UX team presentation page.

• For Mac – Firefox 4.0.dmg (27 MB)
