Geohot has released a iPhone 3GS jailbreak tool named PurpleRa1n, it’s Windows only currently. It’s available now but it’s not an official jailbreak, therefore shouldn’t be used without caution. Some people are reporting it to work, others are not however this jailbreak is missing a lot and also things such as WinterBoard won’t function properly due missing critical patches required for WinterBoard, as reported by Saurik.
If you have to jailbreak straight away use this tool however it may cause problems in the future which you might not get if you wait for the official Dev-Team tool’s which are being released just after Apple sends out firmware 3.1.
