Here's one of those keeper sites that should be on every iOS device owner's bookmarks tab. With so many Redsn0ws, Blacksn0ws, Spirits and all sorts of names that sound like Frosty The Snowman for Jailbreaks in the market, it can prove to be a challenge for you to know which one is good enough to do the trick for your iOS device.
Lucky for us, someone already did the hard work of figuring things out and was kind enough to build us a free matrix that holds the details. From Jailbreaks to unlocks, from the iPad to the iPod Touch 1st Gen, from iOS 1 to every single release to date, from iTunes 8.2 to the current one, the matrix holds every single detail and even gives you a link to download the corresponding Jailbreak or Unlock software. It seems the developer has done a fantastic job in keeping things to date so I'd personally consider this the most reliable, go to source, for a smart hack.
The whole thing is free, so just head on over to JailbreakMatrix.com and start shaping up that iOS baby the way it should've been from the start, as long as you don't mind the risk..
