Since Apple has renamed iPhone OS 4 to iOS 4, we thought we will update our jailbreaking guide for iOS 4.0 for both iPhone 3G and iPhone 3GS. The redsn0w 0.9.5b4 which was released for iPhone OS 4 Beta 4 (now iOS 4) will need an update to work with this version of iOS 4. But the instructions to jailbreak would remain the same. We will let you know as soon as an update is available.
The million dollar question, how long before the new iPhone 4 is going to be jailbroken and unlocked? Well we already know that the iPhone Dev Team has already announced that they are going to release an unlock which will work on the 05.12.01 baseband on all iPhones, provided they haven't upgraded to the latest 05.13 baseband. But since the new iPhone 4 will have the latest baseband, it will be a while before it gets fully jailbroken and unlocked. Another infamous iPhone hacker by the name of Geohot is also said to have a new bootrom exploit, which he has preserved for this new iPhone.
The iPhone hacker behind sn0wbreeze, f0recast and BlackBreeze today accidently put up a picture on his twitter account, showing version 1.6 of sn0wbreeze which promises to jailbreak iPod touch 2G on iPhone OS 4.

A group of hackers are working on bringing iPhone OS 4 over to the original iPhone EDGE (aka iPhone 2G) which was released back in 2007.

The original iPhone EDGE users enjoyed all the firmware upgrades for free up to iPhone OS 3.1.3.
Similar to the hack which enabled multitasking on iPhone 3G and iPod touch 2G running iPhone OS 4 Beta, the following step by step instructions will help you enable Wallpapers support which like multitasking, was locked down by Apple for the mentioned devices.

We told you earlier that multitasking was possible in iPhone 3G and iPod touch 2G on OS 4, provided that you jailbreak the device and edit a N82AP.plist file. A video, which has just popped up demonstrates exactly that on a jailbroken iPhone 3G, running OS 4. Video after the jump.
