An iPhone developer called DarkMalloc posted a video today showing an iPhone 3G running 4.0 beta 1, jailbroken and using Multitasking! But hold on….Apple said we can’t do that!!
Unlike the jailbreak methods shown by MuscleNerd and GeoHot last week, this one claims not to use a new exploit, but update the device in such a way that the jailbreak is kept intact.
This method has been worked on by DarkMalloc, lilstevie and iH8Sn0w. For reasons explained below, this method will NOT be released to the general populous;
1. It cannot restore on a PC, only a Mac can. There is no way to make it run on a PC.
2. Its very very buggy
3. This is meant for developers to test new api’s.
4. it has a 58% success restore rate.
5. It would promote more piracy. Meaning users would illegally download the ipsw and bypass the UDID trap.
It has been a long time since there has been so many new ways to jailbreak all surfacing at the same time, but this just means that Apple has their work cut out to find them. Like you, we hope they don’t and miss at least one exploit.
Below is the video posted by DarkMalloc.
This is a beta release of redsn0w targeted at developers of jailbroken apps.
Please not that this beta is not meant for the average end-user. There are many things “broken” with jailbroken apps in the 4.0beta1 environment right now, and this beta redsn0w allows the developers behind those jailbroken apps to fix their software before the general public gets iphoneOS 4.0.
Because it’s meant for JB app developers, this beta redsn0w does not perform hactivation. You’ll need a properly-registered developer UDID with Apple to get past the activation screen. For similar reasons, there is no Windows version of this beta redsn0w (since apps are developed on MacOSX). Please don’t pirate Apple software.
Anyone other than developers of jailbroken apps porting their software to 4.0beta1 should still be using our previously-released redsn0ws for 3.0 through 3.1.3
This BETA release supports:
* iPhone 3G only (for now)
* Mac OSX only (for now)
* the 4.0beta1 FW only (for now)
YOU SHOULD STAY CLEAR OF THIS BETA SOFTWARE IF YOU RELY ON A CARRIER UNLOCK.
That’s because the beta redsn0w works only if your device has already been upgraded to the stock 4.0beta IPSW from Apple, which contains a baseband update. If you installed that IPSW, you’ve already lost the carrier unlock until the next planned release of ultrasn0w and blacksn0w.

Multitasking on your 3G
Once you are jailbroken, navigate to /System/Library/CoreService/SpringBoard.app/N82AP.plist
Open the plist and change the multitasking key to = True
if the multitasking key is not there, add it
