iDevices users are probably waiting for this. The iPhone Dev Team recently released the newest beta version of Redsn0w 0.9.7 or also known as the Redsn0w 0.9.7b5. The iPhone Dev Team was able to fix all of the sandbox related issues in this new beta version and the good news is, it does not disable the Bluetooth like in other previous beta versions. However, it is only meant for beta testers.
If you will remember, the iPhone Dev Team released the Redsn0w 0.9.7b1 just a couple of weeks back that will serve as a backup plan for the iOS 4.2.1 untethered jailbreak for iPhone 4, iPad and iPod touch 4G. The iPhone Dev Team works hard in fixing all of the issues of the untethered jailbreak and to get it ready for the users. The team also released the Redsn0w 0.9.7b2 to fix native app crashes, Redsn0w 0.9.7b3 to fix bugs related to non-GUI programs such as Facetime, Winterboard themes, and embedded videos in iTunes and Redsn0w 0.9.7b4, which eliminated the need to install and run a separate program for usbmux.
More information can be found in the blog post of the iPhone Dev Team about the Redsn0w 0.9.7 Beta 5. They said, “The fifth beta is now available (testers ONLY please!). Bluetooth is now working (and any sandbox-related issues should be resolved too). Please do not pirate the 4.2b3 IPSW! Only those enrolled in the iPhone Developer program have legitimate access to that IPSW using these links (the links won’t work unless you’re a legit developer currently logged in).”
The Redsn0w 0.9.7 beta is currently for Mac users and Windows users will have to wait a little longer as the Redsn0w meant for Windows is not yet ready for beta testing.

Some users claimed that they cannot jailbreak the Apple devices that they bought recently with Redsn0w. There have been a lot of speculations and one is that Apple might have patched the limera1n exploit that has been used in Redsn0w to jailbreak the iOS 4.2.1 in newer iPhones, iPads and iPod Touches.
Limera1n was first introduced way back in October by Geohot as a jailbreaking tool for iOS 4.1 using a bootrom exploit. Since it was bootrom exploit or in the hardware level, it means that Apple could not stop the exploit from being used in existing iDevices and to prevent users from jailbreaking their gadgets. However, Apple can now prevent their newer iDevices from jailbroken by patching the bootrom exploit.
One user told in a forum that he believed that Apple already patched the exploit to newer iDevices. He said, “I made a trip to the Apple Store today to get an iPad for my old lady (Christmas present). She told me she’d love it jailbroken, so I sat down in front of my computer to redsn0w this 4.2.1 iPad. One problem–redsn0w 0.9.6b6 could not upload a pwned iBSS (hanged at the white screen on OS X, upload timed out and rebooted into jailed state with Windows). Furthermore, the device constantly stalls when attempting to dump its bootrom. This leads me to believe the injection vector used via USB has been patched in DFU mode. Case in point: Any iOS device with a serial number xx050 (this week) or higher might be unable to be jailbroken via the limera1n exploit. Slightly older devices may be invulnerable as well.”
You can find out if you can still jailbreak your iPhone, iPad or iPod Touch with limera1n by looking at the serial number to find out which week your iDevice was manufactured. The serial number can be found on the iTunes summary page or Settings App –> General –> About –> Serial Number. The first two digits of the serial number gives you the factory ID of where it was manufactured and the next three digits (Digits 3-4-5) tells you when it was manufactured.
Based on speculations, new iPhone, iPod Touch and iPad manufactured from the 50th week of 2010 may have the updated bootrom. This is not the first time that Apple did this to stay ahead in the cat and mouse chase with the jailbreaking community. October last year, Apple started shipping iPhone 3GS with newer bootrom to prevent jailbreaking.
