Quick Question - Only Experts

Hi,
I'm running 3.1.2 on a 3G that's jailbroken. I want to upgrade to 4.0 or higher without risking a baseband upgrade and for future unlock-ability. What is the quickest method which does not require a complete wipe and transfer of all files from backup?

Thank you.

Your only way is to use a custom restore to go to 4.1 and preserve baseband. There is no other way.

no way to do it without restore

I'm on Windows. Which program does the trick? QuickPWN, redsn0w, blackra1n, jailbreakme, or any other?
I did not want wipe and transfer the files because I would loose the jailbroken apps. Any efficient backup app out there?

Thanks.

You could use sn0wbreeze but it has a lot of issues for iPhone 3G. What you need to do is find a custom 4.1 made with pwnage tool (google). Then use redsn0w 0.9.6b3 to put the iphone in a pwned dfu state so that you can restore to the custom firmware.

I have the custom ISPW however, I want to backup all my jailbroken apps before doing the wipe. Is there any efficient method out there?

Thanks.
