Psst. We’re not going to tell you where to get it, but if you happen to have some seedier connections, we can tell you that yesterday’s Gold Master Build of iOS 4 works on any iPhone or iPod Touch, whether or not its UDID has already been reported to the dev center. That means, if you know where you’re looking, you can install iOS 4 on your device right now… provided your device is a 3G, 3GS or second or third gen iPod Touch. Make sure to grab the right IPSW for your device.
Better? If you’ve got a 3Gs, you can already jailbreak it, although we recommend being cautious and if you don’t know what you’re doing, wait until the Dev Team releases the new 4.0 compatible PwnageTool… which they swear should be available within the month.
