how do I fix an error (3004) after my update to restore. I really hate apple now. help

What does the SIM PIN have to do with Apple? It's put on either by you or by your carrier, and it is a feature of every GSM phone ever sold.

For error 3004, see: http://support.apple.com/kb/TS3694#error3004

A common cause of this error is trying to restore a phone on a computer that was used to jailbreak some Apple device in the past.

OK, so follow the instructions I linked to.

Jailbreaking has little to do with the computer. iDevices are jailbroken, connecting it to a new computer does not change that.

The tools that are used for jailbreaking also corrupt the network database on the computer that was used for jailbreaking. This can cause problems later until the corruption (usually to the hosts file) is corrected. The symptom is one or more of the error codes that say iTunes could not reach Apple's download or activation servers.

This error was taunting me for way to long but I beat it by adjusting host files.

1. Open Terminal

2. Type "sudo nano /private/etc/hosts"

3. Press Enter

4. Type Admin Password

5. Press Enter

6. Edit to mirror image above.

7. Control+O to save

8. Press Enter to save name

9. Control+X to exit

10. Open Itunes

11. Connect Iphone

12. Update or restore whichever you like (I restored and entered Itunes in DFU mode)

Hope this helps

See my post above yours. If the line containing gs.apple.com is in your hosts file it means that your computer was used to hack or jailbreak some iDevice. So if you know your computer had be used this way in the past this should be the first thing to check.

And actually you can safely delete the line containing gs.apple.com. Putting the "#" in front of it makes it a comment, which is almost as good as deleting it, but deleting it completely will avoid future confusion.

I did the same and you know what? i did not find any lines like gs.apple.com...... hehe

so please tell me what i can do now?
