Apple has released Snow Leopard, the new version of Mac OS X, on Aug 28. It brings lots of refinements, extends the support of 64-bit computing and MS Exchange. The best is its low price point that it only costs US$29. If you’re a Mac user, probably you are considering to purchase the new OS. But for those iPhone jailbreakers, you may also concern if the new OS impacts the jailbreak process.

So, here is the good news. The iPhone Dev Team has confirmed it’s safe to upgrade to Snow Leopard and all jailbreak tools including redsn0w & PwnageTool are compatible with the new OS. Snow Leopard also doesn’t pose any threat to Ultrasn0w, the unlock tool for iPhone 3Gs & 3G. Quoted from iPhone Dev team’s blog, here is what the team mentioned about the status of jailbreak tools:

* You can use redsn0w to jailbreak any iPhone or iPod Touch using OS X, Windows, or Linux. For both 3.0 and 3.0.1 firmwares, you should point redsn0w at the 3.0 IPSW. If you see it hang at “waiting for reboot”, just unplug and replug that USB cable.
* You can use ultrasn0w to unlock the iPhone 3G/3GS, or BootNeuter to unlock the iPhone 2G. Both ultrasn0w and BootNeuter are available via Cydia.
* You can use PwnageTool for Mac to create custom IPSWs with pre-installed packages.

If you plan to upgrade to Snow Leopard, Amazon is now offering a discount and you can purchase Mac OS X version 10.6 Snow Leopard for US$25 only.
