iPhone "not eligible for requested build"-4.3.3, iPhone 3GS

[AlphaDogg]

I just got my iPhone replaced under warranty due to a broken power button. The replacement is on 4.3. I want to do 4.3.3 so I can jailbreak it. I keep trying to update and restore it to 4.3.3, but neither works. Any reason? I tried rebooting, using another computer, redownloading the firmware, manually selecting the firmware through option-click... Nothing works. Any ideas?

Thanks,
Alpha

Are you downloading the GSM version? There are both GSM and CDMA versions of 4.3.3.

I wasn't aware that there was a CDMA iPhone 3GS...

There isn't, but you can't install CDMA 4.3.3 on a GSM 3G. I was just checking.

Alright.. Screw it. I just registered my UDID on my friend's developer account, so I think I will just do iTunes 10.5 beta and iOS 5b1

Edit: Not gonna do this quite yet. Please help me! Is it some sort of network issue (Comcast could be blocking some things..?)

I just installed iTunes 10.5 beta, and it still won't work. Any ideas?

Sorry for consecutively posting so many times. I fixed it by following these instructions: 1) Open TinyUmbrella and in advance options uncheck the box to point to Cydia on exit. Exit TU.
2) Open redsn0w and set device into pwned dfu mode only. Open iTunes.
3) Try the shift+restore to custom fw again.

I wasn't using dfu, redsn0w or a custom fw, so I only loosely followed these instructions.

The easiest way to fix this on the mac is to go into terminal, edit your /etc/hosts file and comment out the line that redirects gs.apple.com to an IP address.

I am restoring to 5.0b1 after 4.3.3 worked. I found a link with instructions on how to downgrade to 4.3.3 if needed, so if I find that I am missing jb features, I will downgrade.

Possible solution

The 'hosts' solution and other tweaks certainly work for some, but not for all...

I found another interesting case and here is the solution.

If you want to upgrade to 4.3.3 and have an earlier version jailbreak TETHERED, Itunes will not upgrade your device.

What you need to do is reJailbreak with a UNTETHERED version.
When the device is UNTETHERED you can upgrade from Itunes. Of course, if you have used an Umbrella before, you also need to clean up the host file.

Worked for me on both Ipad 1 4.2.1 tethered and Iphone 4 4.2.1 tethered.
