     1. Select the hosts file. Then click the Edit menu, and choose Copy.
     2. Then, click the Edit menu again, and choose Paste. There should now be a duplicate of the hosts file named "Copy of hosts".
     3. Drag the original hosts file to your desktop.
     4. Right-click the "Copy of hosts" file and choose Open. You may be prompted to choose the program you want to use to open this file. Double-click Notepad.

  • Make sure that your computer meets the iTunes minimum system requirements.
  • Make sure that your operating system is up to date:
    • For Mac OS X, use Software Update to determine if you need to update your system.
    • For Windows, go to Microsoft's Windows Update webpage.
  • Make sure that you can access the Internet on your computer.
  • You may have firewall or other security software that is preventing your computer from connecting to the iTunes Store. Click here to find out which ports and servers need to be allowed for iTunes Store access.

The first thing that you should do is download itunes from the apple website at www.apple.com/itunes once installed open up itunes and then plug in the supplied usb cable into the ipod and the other end into your computer. From itunes you can then go onto the apple store and buy music from the store or if you have music on CDs you can use itunes to pull the CDs onto your computer and from itunes and clicking on the devices section you can transfer the music onto your ipod. Hope this helps.

You need to uninstall ALL Apple software (iTunes, Safari, Quick Time etc) from your PC then restart and re-download iTunes and re-install.


Hope it will solve your problem
Thank you

Hi,
Here u can follow the steps

Step 1: Make sure you have downloaded the latest version of iTunes if you haven’t already. Download iTunes 8.2 from the link given below.
Step 2: Now connect your iPhone with your PC. You must connect it to a single usb port on the backside of your computer. Do not use any usb hub or the ports in the front as this could cause an error during update process.
Step 3: Start iTunes 8.2. Sync your iPhone with your PC so that iTunes backs-up all your important data including settings, apps, music, contacts and photos.
Step 4: You will now have to download a custom cooked firmware for your iPhone version (2G or 3G). I can’t post the download links for these files for the reasons you all know very well. Just Google “iPhone 2G Custom 3.0” (If you are using iPhone 2G) or “iPhone 3G Custom 3.0” (If you are using iPhone 3G) and use one of the torrent links to download the custom created .ipsw file.
Step 5: Once you have downloaded the required .ipsw file, Copy/Paste it into this location:
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows 7)
“C:\Users\[username]\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates\” (Windows Vista)
“C:\Documents and Settings\[username]\Application Data\Apple Computer\iTunes\iPhone Software Update\” (Windows XP)
Step 6: Restart iTunes. You will now be prompted to install this firmware you just download. Just close this prompt dialog by clicking on “x” from the top right-most corner of the window.

Step 7: Now you will have to restore your iPhone to this custom firmware 3.0 that you just downloaded. Click on your phone from the sidebar in iTunes to get to this screen as shown in the screenshot below:

Now press and hold left “Shift” button on the keyboard and then click on “Restore” (Not “Update) button in the iTunes and then release the “Shift” button.

This will make iTunes prompt you to select the location for your downloaded custom firmware 3.0. Select the downloaded .ipsw file and click on “Open”.
Step 8: Now sit back and enjoy as iTunes does the rest for you. This will involve a series of automated steps some of which are highlighted below:

Don’t do anything silly at this point. Just wait while iTunes installs the new firmware 3.0 on your iPhone. Your iPhone screen at this point will be showing a progress bar indicating installation progress. After the installation is done, iPhone will restart automatically and you should now have a fully unlocked and jailbroken iPhone 2G. iPhone 3G on the hand will only be jailbroken, not unlocked. iPhone 3G users will have to wait for Dev-Team to release ultrasn0w on Cydia in order to unlock their phones.
Step 9: Once you are done with the unlocking and jailbreak process. You can now restore all your settings, apps, music, contacts and photos to the newly installed firmware version 3.0 by restoring the backup that you made in Step 3 from iTunes.

Feel free to ask me any question here should you run into any problem during the update process.
