________
Welcome Address and Keynote:
Quite a strong start and powerful Introduction to a great event. They started with introducing the all the Google staff to the audience and then moved on to talking about Google itself and its operations in Egypt and the Middle East.

Google in the Middle East:
One of the biggest and most impressive presentations during the event. The session covered a very wide range of topics starting from Google's core search engine and how it has been made to fit the needs of Arabic speakers surfing the web all the way to development technologies for platforms like Google's App Engine and Android. One of the highlights of this session is the HTML5 demonstrations, they introduced HTML5 to the audience, highlighted the new features of HTML5 like the canvas and showed us how all this is compatible with Google's own Chrome Internet Browser.

Work in Open Source:
Another very interesting session presented by Chris DiBona. The session talked about open source software, its advantages to both consumer and developer as well as all of Google's open source projects like Android for example.

Google AppEngine & Google Web Toolkit:
We were given a quick tutorial on Google's new platform called the Google App Engine. The required software and SDKs were distributed among the attendees so they can follow up on the coding session instantly. The tutorial covered the the basics of App Engine. The Google staff then announced that there is a coding competition taking place through out the rest of the day and the best App Engine application is to win an Android phone as a prize. At the end of the day each team presented us with their application. They were quite impressive and creative especially for people who had no prior experience in App Engine and were coding on it for the first time. A panel of judges from the Google staff was set up and the winner(s) were chosen.

Almost every session during G-Egypt was great, interesting and taught us something new. I'm very happy to have had the opportunity to attend such and event and plan to attend the next event.

iPod Touch 2G Jailbreak Log


Well since I now have a Mac (Snow Leopard) machine and Xcode, I can start developing applications for my iPod Touch. However, Apple's regulations require that i need to purchase a developer's license even if its JUST to test my app on the actual device. Since I am learning/developing on the iPod Touch for educational purposes only and have no intention of publishing to the iTunes store I find little choice but to jailbreak the ipod touch. This post will show the steps/missteps I've gone through to do such a procedure along with links to the tutorials I've used.

First off, in a previous blog I've shown how to jailbreak the iPhone/iPod Touch using the blackra1n tool. The problem I faced when starting off was that I was working with Xcode v3.2.4 and iOS SDK 4.1, iOS firmware 3.1.2 was no longer supported on that SDK so I either had to upgrade my device's firmware or downgrade the SDK. I soon discovered that the blackra1n tool only works for firmware 3.1.2 and I had to find another alternative for jailbreaking. Here are the steps I've gone through:
  1. Downloaded the ipsw recovery image (firmware version 4.0) that I will need for the jailbreak. My device is an iPod Touch 2G so if you have a different device you will have to download a different ipsw image that will be compatible with your device.
  2. Downloaded the latest Pwnage tool for Mac (you can use Redsn0w for windows)
  3. Follow the steps the jail breaking application tells you (they are pretty self explanatory) or if you feel lost follow this tutorial to jailbreak your device.
  4. Now what happened to me here is the iPod booted up into recovery mode even though it should have been jailbroken by now. It went into a state where even iTunes failed to recognize it and therefore unable to restore/recover it. Why this happened is unknown to me at this time. What I did now is  force put it into recovery mode by pressing and holding down the power and menu buttons at the same time. It will prompt you to shut down the device, go ahead and shut it down.
  5. Now, while holding down the menu button, plug your device to your computer using the usb cable. This will make the device start up in recovery mode and launch iTunes. This time iTunes should be able to detect the device, if it didn't try repeating the recovery steps again.
  6. I used my old ipsw image for firmware 3.1.2 to try and restore the ipod back to its original state (for Windows press shift and the restore button in iTunes, for Mac press the option button + restore button). This time the ipod surprisingly booted successfully into the jailbroken 4.0 firmware.
So here we are, a somehow working jail break for the iPod Touch 2G. Your steps may vary according to your device. If there are any question/comments/suggestions please feel free to leave a comment.

Jail breaking the iPhone/iPod touch

Image representing iPhone as depicted in Crunc...Image via CrunchBase


This is a very simple and straight forward guide to jail breaking your iPhone or iPod Touch. If you get stuck and have any questions feel free to ask here in the comments or contact me on twitter.

For PC users
(note: make sure any software you download is compatible with your device before you use it, check both your device's generation and the firmware currently installed on it)
  • Step 1: Download iTunes and restore your device if you must.
  • Step 2: Download the Blackra1n tool for windows.
  • Step 3: Simply have your device connected to your PC with the USB cable, make sure iTunes is not running and run the Blakra1n.exe file that you have just downloaded.
    That's it, enjoy your new jailbroken phone!
    ____________
  • Step 4 (optional): If you have iTunes version 9.1 or above you might get an error saying "The program can't start because ASL.dll is missing from your computer", if that happens copy the contents of the Blackra1n folder to these directories:

    32 Bit – C:\Program Files\Common Files\Apple\Apple Application Support
    64 Bit – C:\Program Files (x86)\Common Files\Apple\Apple Application Support
  • Step 5 (optional): Once you have the files copied simply run blackra1n.exe from the new directory or create a shortcut for it on your desktop and run it from there. Everything should run smoothly from here. Enjoy your new jailbroken phone!
I will add a guide for Mac users soon, keep checking back.

Mac OS X Intstallation log [Last Update 22/7/2010]

Mac OS X Snow Leopard desktopImage via Wikipedia

This is a log of events and steps taken to install Mac OS X Snow Leopard to on a normal PC. It will be updated as I progress.

  • Attempted to Install Mac OS X 10.4 on a Mac Compatible machine. After successful install the machine restarts and gives an error message asking to "Reset the computer". Several repeated attempts later also failed. I Suspect an error with the Hardware itself.
  • Set up a Hackintosh USB flash drive. Attempted to install it on the same machine to confirm whether its a hardware or software error. The error still persists, this time the machine restarts during the Apple logo screen.
  • Set up Hackintosh successfully on a different machine (will be referred to as Mac_B from here on). Mac_B is now currently running Mac OS X 10.6 Snow Leopard.
  • Downloaded the iPhone SDK 4 and XCode 3.2.3 (requires free ADC account) and install them. The installation failed because it requires the OS to be updated to at least Mac OS X 10.6.2 (current version 10.6)
  • Downloaded the latest update for Snow Leopard Manually (must choose the "Combo" update if you plan to jump the versions in between your current and the latest). After the update Snow Leopard starts up but gets stuck on a blue screen that it refuses to go past.
  • Tried re-installing Snow Leopard via USB flash drive again, the installation seems to have rolled it back to Mac OS X 10.6 and left all the files on the hard disk untouched.

Warning to all Android users in the MiddleEast

After months of hunting down Android phones in the market and finding the best deals, I have finally settled on the HTC Legend, which is a fantastic Android phone. However, there is a slight problem, it doesn't come with the Android Market App pre-installed! After several Google searches (do you see the irony in this?) I was unable to find any legit way of downloading the Android Market to my phone. Android phones distributed in the Middle East (or from the Middle East as I have found some EU countries also suffer from this problem) do not have the App installed as it is not supported in this region, and Google does not provide the App for download.

There are two ways to get around this:
Option 1: I found several users on various forums complaining about this problem. In order to fix this problem to resorted to rooting or flashing their phones' OS, something I do not recommend unless you know absolutely what your doing and also because it could void your phone's warranty.
Option 2: The easy option is to download free alternatives to Google's Android Market like SlideME or AndAppStore (mind the naughty apps). They may not have all the Apps found on Android Market but they are quickly catching up and might someday even exceed it. There are several other alternative markets out there but these two seem to be some of the more popular ones.

You can bide your time with these market apps and hope that the next update for your Android phone will contain the Android Market, or avoid the problem completely and import a phone you are sure will contain the App like the Nexus One.
