On Monday, Apple released firmware 4.0 for the iPhone and iPod touch devices. This of course was a major upgrade.
As advised, you shouldn’t have upgraded your devices if you have previously relied on our tools for hacktivation and/or a carrier unlock.
With that said, today we are releasing PwnageTool 4.0
PLEASE READ THIS ENTIRE POST CAREFULLY, THERE ARE KNOWN UPGRADE TRAPS AND DIFFERENT UPGRADE SCENARIOS THAT NEED TO BE FULLY UNDERSTOOD AND CONSIDERED BEFORE USING THESE TOOLS.
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.
