With the release of iOS 4.0.2, you can’t jailbreak most iDevices anymore except for iPhone 3G, iPod Touch 2G (non-MC models) and recently iPhone 3GS with old bootrom using custom firmware by Kaatje which isn’t out yet. We’ve prepared a simple guide on how you can jailbreak iPhone 3G with iOS 4.0.2 using the latest redsn0w release.
- Download iOS 4.0.2 and iOS 4 for your iPhone 3G. Place it on your desktop for easy access.
- Download redsn0w 0.9.5b5-5 [link at the end]. It’s available for both Mac and Windows.
- Download and install iTunes 9.2.1.
- Now connect your iPhone 3G to your computer and using iTunes, upgrade to iOS 4.0.2. This can be done using iTunes as described here.
- Now that you have iOS 4.0.2 on your iPhone 3G, you’ll have to jailbreak it by using iOS 4.0 (NOT iOS 4.0.2) with redsn0w 0.9.5 Beta 5. Click browse and point it to iOS 4 firmware and follow the instructions on the screen. [Vista users might need to run redsn0w as administrator]
- Once you’re done and the iPhone reboots, you should have a jailbroken iPhone 3G.
- To unlock your iPhone 3G, follow this guide here.
- If you want to enable/disable multitasking or background wallpapers on your iPhone 3G, use zToggle. We don’t recommend it though as it will suck the performance and battery out of your iPhone.

Have u tried restoring the firmware and trying all over again?
atleast 7 times…no exaggeration
Try restoring to 4.0.2 by putting your iPhone in DFU mode and then trying the process again. Also, tell me your device model. Keep me updated
Its an iPhone 3G
still nada…I think I’m screwed. Can’t get passed this “waiting to reboot” screen despite my best efforts. I guess this works for some and not for others. And I’m on T-mobile so this REALLY sucks.
I am not able to see ipws file after downloading iOS 4.0.1 and 4.0 on my desktop, please help
So, I have done this in the past and rebooted bc of the incredible slowness and losing MMS. Should I give it another shot, or am I doomed for the same thing again?
What happens if I point redsn0w to 4.0.2?
will it not work?
because 4.0 doesn’t work..
worked perfectly for me, here is the exact name of the ipsw for 4.0 software i used;
“iPhone1,2_4.0_8A293_Restore.ipsw”
i did this with “redsn0w 0.9.5 b5-5”
on an iPhone 3g model: A1241

I do too. Activity meter showd 90+% usage, it is sluggish in response and battery gets deterioated fast
Hello,
I am not able to jail break my iPhone 3GS device. I have by mistaken uploaded the OS of my device to 4.0.2. But now I am not finding any way to Jail break and unlock my device. It shows “Emergency Call” screen only. I have tried with PWnagetool for iphone 3gs 4.0.2 and also used redsn0w 0.9.5b5-5. But then also not able to jailbreak my device. Please help me to solve this problem.
I just want to put mobile spy on my daughters iphone. I’m not trying to change carriers. So after step 6 the phone is jailbroken and that should be it, right? I wouldn’t need to do step 7 to “unlock” the phone?
your a bad man
