You won't lose your apps if they have been downloaded legitimately.

You can upgrade and unlock, google "dev blog" and read up on how to do it.

you can't jailbreak os4 if you do an official upgrade, but there is a way to keep your downgraded baseband and upgrade, have a look at [url]www.iclarified.com[/url] for step by step instructions

u can download a custon firmware of 4.0, with it jailbroken already to avoid the official update,
thats what I got with mine.
3GS with custom firmware and retained the old base band and also unlockable.

Any links to that guide, I'm also still at 3.12 JB on my 3GS - haven't gone to 4.0 yet as I didnt know there was a custom firmware ?

oooo where is this then pal?? sounds goood :-D the custom is basically the same as apples 4.0 i am guessing then?

i just noticed you said avoid the update, i dont have to install the 4.0 update when connected to itunes anyway because i saved my date to cydia. Is it worth installing the 4.0 custom?

How can I check the baseband and bootrom on my 3Gs please, is there a program for windows to do this easily ?

Also does the bootrom change, when you do an update or does it always remain the same ?

Thanks
