How to go from 3.0 to 4.x ?
Don't fix what's not broken let me NOT upgrade my jailbroken iPhone for a (long) while.
Now I cannot find any description how to go from 3.0 to 4.x
Which tool, which procedure?
I use Windows.
If you do have a 3G (you posted under 3G subforum) then redsn0w 0.9.5-b5 will solve your problems. Search.. before posting. There is an existing thread I replied to today regarding the same topic.

If you have access to a mac, then you can use either redsn0w or pwnagetool. Pwnagetool 4.0.1 gives you the ability to block baseband update - that means you can go back to iOS 3.x if you don't like 4.x
All this has been discussed in existing threads.. You are not unique in your situation. Try harder with the search function next time before creating yet another duplicate thread.
