Hi please excuse my ignorance but I have just recently used spirit to jalbreak my iphone 3gs 3.1.3. Everything is working well and Ive had no issues, Cd someone please advise can I now upgrade to osi4 software or will this affect my jailbreak I am teaching myself on this and apologise if this is a really silly question.

If you upgrade to iOS4 you will lose your jailbreak.
