I have already updated a 3G to 4.0 and now want to jailbreak and unlock. Is this possible? I've read this forum but most situations refer to iPhones not yet on 4.0
Thanks

Jailbreak and unlock 3G on 4.0

Yes, I believe a program called Redsnow will JB and Ultrasnow will unlock it?
You cannot unlock only.
You first need to JB and then install the unlock program thru cydia.
Really? hm... Anyone that JB'ed knows if it's slower or something than the original firmware?
It only gets slower if you load a bunch of packages that run constantly in the back and if you install themes, custom wallpapers and icons, lockscreen stuff etc..
If you just JB and only install ultrasnow to unlock you shouldnt notice much lag.
Im sorry im being paranoid, but even without any background running packages etc it "MAY" be slower than the original? I'm just saying because when I JBed with 3.1 I believe, battery life was comp[letely drained out and performance was sluggish as hell. Now that I've gone 4.0 original it just snaps.
Give it a try, if you dont like it go back to stock firmware.
Just make sure you dont enable multitasking or homescreen wallpapers thru redsnow cause that could slow it down also.
Only way to really tell is to try it.
If the iOS is already updated to 4.0 on the 3G, would one need to download the 4.0 firmware and follow the instruction as indicated in iClarified that Applejuiced linked to? In other words, can I just use RedSn0w for jailbreak without going through updating the iOS again? Thanks.
Yes, you can skip that part and just run redsnow to JB it if you're already on official 4.0
phew! ok haha. Btw, you said that if the iphone has already the ios4.0 official installed then you can just JB with redsn0w without restoring. How's so? redsn0w still asks you to load a firmware... should I load which one? The one that itunes downloaded?
If you are already on official iOS 4 firmware, what would be the point in doing the same thing again, you can skip that part.
Just run Redsn0w.
Word of Advice
Don't enable the multi-tasking and all of the other "non 3g features". I've done it and at first everything was wonderful, but now, everything has gone to hell for some reason.
There is so much lag I can barely even answer phone calls in time, I actually have that Crank ring tone that sounds like the phone is dying, well now when it rings it LITERALLY sounds like it is dying. My co-workers actually think it's hilarious, but it sucks when I actually have to answer the bloody call..
But, funny none the less
Trust me, multitasking, background wallpaper is terrible on the 3g, just use it for the unlock and thats it. For once I'm actually saying to keep it the way they intended it to be (other than the unlock/minor jbreak).

Well said.
Now jail broken and unlocked via ultra snow. The recommendation was not to install multitasking so I didn't. All is well and it was an easy process even for a novice like me. Thanks for the input folks.
Joining the not wanting to start a new thread bandwagon
Have a 3GS with 05.13.04 firmware running 4.0 that's never been jailbroken before. Getting an iPhone 4 and wanting to unlock the 3GS to give to a relative in china. Impossible now? Can I go back to 3.13 or whatever last version was, unlock it and update to 4? Not sure if they will even care that it is 4.
Thanks in advance, I know you guys get slammed with these questions nonstop

This thread is about 3G phones, your 3GS is entirely different.

I've found a way to make multitasking work wonderfully on 3G. I had all the same problems you guys have been having when I first jailbroke and enable multitasking and homescreen wallpapers. I restored to a stock firmware and then once again jailbroke and enabled multitasking, installed cydia, but did nothing else. Then I downloaded backgrounder and remove recents. I used backgrounder to set global backgrounding permissions to off, with exceptions for Safari, Pandora, and other apps I actually use. This way apps I just open, such as settings or clock, don't keep hogging memory. My phone has been working like a champ ever since.
