Apple ipod

How I can upgrade to Mac OS 4.0 on my iphone if I have already jailbroken?

The jailbreak is version 3.0 and was wondering if I can recover my iPhone or anything before downloading OS 4.0 on my iphone … My iPhone 3G is a 16G Thanks in advance

If you update the firmware, which will overwrite the jailbreak. You will need to have a restaurant and Prison Break again. I do not know if the leak is a good idea, the current 4.0 jailbreak is still in beta and does not work correctly. Wait for a months or until they give off a great escape from prison 4.0.
