The iPhone Dev-Team has released a version of PwnageTool which can jailbreak many devices with iOS 4.0.
Each supported device has few different scenarios that users need to consider when performing the upgrades, you need to check below and perform the upgrade in the particular way that matches your current device state.
NB: With PwnageTool 4.0 certain devices are not supported this is because they are not supported in iOS 4.0 or they are not supported by our software. We’re working on ways to get past these restrictions.
* iPhone 2G – not supported
* iPod Touch – not supported
* iPod Touch 3G – not supported
PwnageTool 4.0 only recognizes the official IPSWs that came out yesterday. If you had developer access to the “4.0 GM” IPSWs, do not try to use those.
