Hey there Palmer
How are you?
Well, I have an iPod Classic, it gave me the error -1436 error and would not restore on iTunes.
I did the following:
My Boss (@work) has a fairly old iBook but it has OS-X, so I decided to give it a try and connected my iPod to it.
The system showed a window telling me that the disk is not MAC formated and needs to be validated prior further action. Snce it is a Mac product, I thought "yeah, go ahead".
It then opens the disk manager utility for the Mac and showed the disk. It's window has some tabs, one is to verify the disk, so I verified it. Guess what, it had some invalid clusters.
Then I formatted the iPod to OS-X Plus file system (next tab to the right). After formating the iPod, I "ejected" the iPod and reconnected to my PC. The Windows iTunes found an iPod with Mac file system and asked me to restore it. As I clicked on the "restore" button, I crossed my fingers as this was the last resource I have.
Finally, after the file extraction was done, it began to restore the iPod!!
I'm so happy about being able to restore the iPod that I decided to share with all you guys this solution as it is the most usefull, in my opinion.
Hope you can find someone with an iBook or a desktop Mac, so you can fix yours.
If it works for you, make sure to share the tip!!
Kind regards

3GS froze, then said Activation required, now fails to restore with unknown error (1)

My 3GS froze while using Navigon, then showing a pop-up saying "Activation required". When tapping the pop-up, an unusual white question box regarding location service shows up, after tapping "next" the process hangs. Connected to iTunes later, same procedure again, hangs again. When trying restore with iTunes, the whole load process looks ok, but at the end fails with "unknown error (1)", probably when trying to rstart the phone. I tried all variations (restore mode, DFU mode, hard reset) but no luck. The phone was recently officially unlocked (AT&T), could this be a factor? Or is this a harware problem? Any ideas aor hints welcome.
Thanks,
Manfred

Thanks for the pointer to the KB article. Error 1 is missing from the list provided by iTunes (more information), but I was afraid it means hardware. Will try on another computer, but I'm afraid the phone is sick.
Thanks,

Check for hardware issues
Related errors: 1, 3, 10, 11, 12, 13, 14, 16, 20, 21, 23, 26, 27, 28, 29, 34, 35, 36, 37, 40, 1000, 1002, 1004, 1011, 1012, 1014, 1667, or 1669.
These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.
Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.

Hello there, BundyA.
Error 3 is usually associated to security software settings. The following Knowledge Base article provides some great information and links for troubleshooting the issue:
Resolve specific iTunes update and restore errors
http://support.apple.com/kb/ts3694
This section should prove useful:
Configure your security software
Check your security software and settings, which can block ports and prevent connection to Apple servers during update and restore.
Common errors: 2, 4, 6, 9, 1000, 1611, 9006, 9807, 9844. Sometimes as a result of this issue, a device might stop responding during the restore process.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

That is either going to be a hardware failure or your phone is jailbroken and something has gone awry with the baseband.

Plug your iPhone into iTunes and update it to the latest supported version, which is 4.2.1.

I have tried to hold the "home" and "power" button to reboot
I have tried powering it off
I have tried, to unplug the cable, hold the "home" button and then plug it in.
Can't check the SN or warranty, cause it is stuck in restore mode.
Is the hard drive gone? Should there be something replaced.

Error 1 or -1
This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.
