As you are already aware, there’s a jailbreak solution for the iPhone 3GS and it hasn’t been developed by the iPhone Dev Team. And while the Dev Team is still working on its own version, the purplera1n has been updated. The jailbreak solution has now support for that upcoming Windows 7 and it will work well on 64-bit systems too. Other improvements include various kernel patches, correction of terminal errors, an enhanced payload execution and more. Winterboard support is expected in a future version. OS X compatibility is also coming in a future update so hang on to your hats if you’re not using a Windows-based computer at home. And just in case you upgraded your iPhone to OS 3.1 then you should also put your jailbreaking thoughts at ease for now.
