Looks like WinPwn 2.5 will be here soon. WinPwn is the Windows version of PwnageTool for Mac. It jailbreaks your iPhone or iPod Touch and also unlocks 1st Gen iPhones. So far it’s not available for download yet but it will support firmware 2.0.2. Here’s some feature notes and screenshots:
– QuickPwn support (2.0/2.0.1/2.0.2)
– DFU helper
– Automatic updater (yay no more downloading new installers)
– Plus much more….
