You probably/may already have a copy of the 4.3.1 ipsw in your 'iphone software updates' folder (google it's location for your OS), if not then you can download a copy from here, Redsn0w will ask you to 'Browse' to an ipsw, so click browse and from the pop up window, navigate to & select the 4.3.1 ipsw and then hit next and continue the process. If you're on windows 7/vista make sure to be running as Admin and in XP compatibility mode.

How do you put it on administrator because I'm on vista?

That I can't tell you as I'm a Mac user, but I'm sure google has the answer.

Thanks for that Venus thats what I thought that itunes would create an ipsw file since its a software update, with regard to baseband preservation i'm in the middle of | How to Update Your iPhone 4 Without Upgrading the Baseband (Windows) 4.3.1, Iclarified, but my baseband was 04.10.01 before updating and still is now after so I dont have to follow this process do i?

You have nothing worth preserving so just forget about that tutorial and run Redsn0w

(04 Apr '11, 18:46) venusanann venusanann's gravatar image

Cheers for that, how do you know when to preserve baseband and not? Not a cheeky reply a genuine question

(04 Apr '11, 18:49) Bornsrvr Bornsrvr's gravatar image

When you have one that is unlockable i.e. if you had the iphone4 - 1.59.00 baseband which came with either 4.0, 4.0.1 or 4.0.2, then you'd want to preserve that, as it's the only iphone4 baseband that can be unlocked by ultrasn0w

Thanx yet again

Of course, that's how Redsn0w works, will need to browse to a copy of the 4.3.1 firmware for your idevice though.

Where can I download a copy of 4.3.1 to put in a file if I already have it installed, or can't I?

(04 Apr '11, 18:16) Aaron9266 Aaron9266's gravatar image

On windows its usually right click and choose run as admin and to run in compatibility mode, again right click >properties>compatibility>choose your settings

Right-click redsnow.exe, properties, compatibility tab, run in xp sp3 mode, check 'run this program as an administrator' at the bottom, click ok.

If you recently updated you will ahve a copy on your computer or you could download one, what system do you have

(04 Apr '11, 20:30) Bornsrvr Bornsrvr's gravatar image

On windows 7 it will be in user/name/appdata/roaming/apple computer/itunes/iphone software update or whatever your device is.
