In our preview article, we took a first look at Sn0wbreeze v1.3. , and we told you that you should not expect any tool updates from the iPhone DevTeam or GeoHot. Well it seems that the iPhone DevTeam is working on an update for PwnageTool , and they ask iPhone 3G and 3Gs users to not rush into an update.
PwnageTool will allow you to create custom firmwares that you can use to jailbreak your iDevices, and not update the baseband. That way you can still use the existing tools to unlock.
