Do you all jb 3.1.3 user will restore to original setting before upgrade to iOS 4?

omg ,if yes .. i need download original 3.1.3 firmware and IOS 4 firmware ...quite long waits...I CANT WAITS for this ... XD

Hmm,finally i got two 3Gs and 4G firmware. I downloaded 3GS firmware for restore my jb 3gs to original setting 1st then only update by 4G firmware...
but i see several got some problems after upgrade 4G...omg,,i should wait more stable ver is out?

3.1.3 jailbreak -> upgrade to IOS 4,can work?
or must non-jb version to ios4 ?

I am trying enable Internet therthering and connect to my laptop , but no work at all. I only saw the network Apple adapter shows network cable unplugged in network connections of control panel (laptop)! Since I updated my 3Gs to ios4 ,this is my 1st time use Internet therthering ... My last used it is the iPhone with3.1.3 os. I worry this is happening because I had upgraded to ios4 ... Help!note, my current internet is GPRS,but I dun think that is problem.because I can surf net in iPhone now...
