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.

So i did the instructions but cant get past the first few steps cause, it says it does not recognize the ios. yes its the 4.0 and not 4.02
U HAVE TO CHANGE THE EXTENSION OF THE .ZIP FILE TO .IPSW, DO NOT UNZIP THE FILE, JUST CHANGE THE EXTENSION, THEN HIT BROWSW, AND DOUBLE CLICK IT, THEN FOLLOW INSTRUCTIONS, its pretty easy actually, the changing the extension part was what made me raise my eyebrow for a minute
1. Can you upgrade a jailbroken/unlocked 3G iphone directly using itunes to 4.0.2?
2. Should you do a restore before updating to 4.0.2 using itunes?
3. Do you have to remove the T-moble sim card before updating?
Managed to download redsn0w 0.9.5b5-5 & ios 4.0 on my machine and also my 3GS has ios of 4.0.2. Stuckup while pointing firmware on redsn0w 0.9.5b5-5, there are no .IPSW files but only has .IMG3 files. Pls. help/assist this step onwards.
ok so ur site would have been really helpful EXCEPT the fact that nobody effing told me that you cant jailbreak it after youve already downloaded the stupid ios 4.0.2 firmware. right? you can only jailbreak it while ur downloading the new crap… ugh! why the hell didnt those douche bags just offer all the jailbreaking stuff on the phone to begin with?? that would make it SO much easier for us non techies! all i want is my damn text tones!!!
The instructions are very clear. Nobody is going to come and tell you that.
I just want to know something. I’m a newbie to apple stuff. If I have a iphone 3G running under 4.0.2. Do I really have to follow the steps in downloading 4.0? I’m asking because I don’t see any implication based on the guide. Hope you can guide me then.
Yes, you have to download 4.0. You’ll have to point redsn0w to iOS 4.0 firmware, that’s the only way you can jailbreak your iPhone 3G running iOS 4.0.2. This is how it works.
I had download both iOS 4.0.2 & iOS 4 along with redsnow 0.9.5b5-5 for Windows and try to jailbreak my iphone 3g but it seem that redsnow cannot find the IPSW file. This is what I did before I download iOS 4 and iOS 4.0.2 file, I went on to the iTune and upgrade the firmware to iOS 4.0.2.
Any idea what i need to do to get it done?
you should download a good ipsw from any other website
redsn0w will only recognise the iOS 4.0 firmware file and not iOS 4.0.2

Either you’re not using the correct redsn0w version or the firmware version isn’t correct.

I have a 3G and successfully JB’d/unlocked it following your directions. My problem is the phone became so slow & unresponsive I had to restore it. I can’t see that others have this issue, so is it maybe something I did wrong? I wasn’t running any themes or other software known to slow the phone. Any suggestions would be great.

Mine did the same thing. I just restored back to 4.0.2 and will worry about jailbreaking later. The features are awesome but the speed is just impossibly slow.
I have done this following the directions to this strictest degree. I can’t get passed the “waiting for reboot.” I’m using 4.0 as the firmware. It accepts that w/ no problem. But for 2 days I’ve been stuck in “waiting to reboot” everytime I try it. Please help.
