Unlocked 3GS...How do I upgrade firmware? HELP!

Hi Everyone. Hope someone can help me here..

I bought an unlocked 3GS late last year on the classifieds. It was a PAYG O2 phone but when I bought it it had been unlocked to any network and didn't come with the PAYG SIMcard.

in settings it says

modem firmware 04.26.08
version 3.0(7a341)

Now some of the apps I want to use require the latest 3.1x firmware. I've read all through as many posts here as I can and I just can't get me head around, or understand, how can you upgrade the firmware without turning it back to an 02 phone?

Can someone enlighten me as to whether this is possible and how?

Well I've just read that and the comments section is basically full of folk saying that different features or functions of ther phone do not work properly or at all after this procedure....

Has anyone reading this actually done this procedure with a phone of my spec and had it all work afterwards?

Its fine, read the unlocking thread for loads of people from AVF which have used it with no problems. The comments you are reading were probably for earlier versions of the software.
