What you need Before we begin, you need:
An iPhone 3G or second-generation iPod touch already running IOS 4, has been active in iTunes.

How to Jailbreak Your iPhone 3G/iPod touch 2G and Enable Multitasking, Home Screen Wallpapers, and More for iOS 4
Start redsn0w and that the image of the internal oversight office 4.If you have installed the device IOS four, you should be able to find the hard disk's internal oversight office has 4 image C: \ Documents and Settings \ [user name] \ Application Data \ Apple Computer \ iTunes \ iPhone Software UpdatesIn Windows or ~ / Library / iTunes in / iPhone software update in OS X in the file name should look like what the iPhone1, 2_4.0_8A293_Restore.ipsw (That's my so-called).
Decide what functions you want enabled.Once you navigate to the image and click Next, redsn0w will prompt you to select what features you want to escape during the operation.I chose to install Cydia (package manager mentioned above), to enable verbose startup (which shows in detail what the text stream, as long as you power on your device will be a lot), so that multi-task, to the home screen wallpaper, the percentage of the battery.Your preferences, then click Next.
Into your computer and iPhone 3G or iPod touch 2G and turn it off.Your phone should be shut down, and then continue with the jailbreak process.Therefore, through the USB connector to plug it, and then until the "drop" option, hold down the power button, power the latest slide show and then leave.If your device is plugged on and off, click Next to continue.
Put your phone into DFU mode.At this point you are prompted to enter DFU redsn0w mode.The process, such as the redsnow detailed guide is this:
Hold down the power button, shut down for a few seconds. Do not release the power button, hold down the home key for 10 seconds. Does not release home button, press the power button to stop.30 seconds to add a home button.
Watch your device to restart the escape work even though it's magic.If you enter into DFU mode correctly, you should do with your desktop as the rest of the process, it is to place your iPhone.Your phone will restart and you will see a screen that says "Download Prison Break Data" (on), followed by the NOR flash screen, and then you see the following.You do not do anything, but at this point to sit down and watch patiently.
When redsn0w has completed the jailbreak, your device will restart the Office of Internal Oversight 4 back and multi-task, the main screen wallpaper, and all the features you will be lost.
How to handle multiple tasks 3G, iPhone? Of course, you can multi-task processing, but can the iPhone 3G deal with it? (After all, Apple did not release the equipment of these functions, because they made it clear that it can not handle it.) In my experience, so far, it is true, no more slow or no, but I did not install the cabexcited IOS 4 with my iPhone 3G performance in the first.So, for me, the ability to multi-task, does not seem to really poor performance, it seems no better.
In summary, then, I really do not know if I want to uphold the Office of Internal Oversight 4 or downgrade back to 3.1.3 jailbreak IOS.One thing is certain: I do not intend to run the stock IOS 4, because it is the choice of last resort.I do not understand the subtitle, the Office of Internal Oversight 4, I want to, but I have only poor performance.
