Upgrading from iOS 4.3.5 to iOS 5.1 - step-by-step guide?

[Pinmac]

I need to upgrade from 4.3.5 to 5.1 but am very nervous when having to deal with iTunes as wiped an iPod Classic a few years ago. Is there a step-by-step guide anywhere which tells me exactly what to backup and so on please? I know that there's a sticky for if you have a problem with the upgrade but I haven't got there yet.

Below you will find some links to help you, one is a visual which is very good. Make sure you have the latest version of iTunes on your PC/Mac and backup everything. It's a good idea to also disable your virus protection for the duration of the update.

And here's a troubleshooting thread, although I don't think you will need it, but just in case.

Thanks, Leelai, haven't had time to look at the video yet, will need to find a quiet few minutes. Have hit the first problem. I can't update from iTunes 10.5.2.11 to 10.5.3. It fails and suggests that I download manually. I download but then there doesn't appear to be a way to install. So I thought I'd uninstall iTunes and reinstall (which I've had to do before) but I'm unable to uninstall either. I get an error message saying "Error writing to file: C:\Config.Msi\612d378.rbf. Verify that you have access to that directory." Any suggestions from anybody as to what I can try next?

Forgot to say that I am the administrator.

That's very unusual that it won't let you update iTunes. I can't say iTunes is my friend either. I'm hoping someone else will chime in here to figure this out.

Just watched the video - really useful and just what I was looking for. Still can't get iTunes to update though so if anyone can help I'd be really grateful.

Did you disable your virus protection? This caused many members problems and may be the reason you can't update iTunes. Try it and see.
Have a look at this thread also for troubleshooting

Thanks for the suggestion, Leelai, but I tried it with the anti-virus switched off and still the same result. Don't know where to go from here.
