Free Iphone Unlock

The iPhone Dev Team released the Redns0w 0.9.10b4 that fix the iBooks and launchd socket related problems.
Just a few days after Corona Dev Team released their own version of iOS 5.0.1 Untether to fix the iBooks issue, the iPhone Dev Team revealed their own version of the fix.
According to the blog post of the iPhone Dev Team, “The b4 version of redsn0w incorporates the 5.0.1 fix for iBooks, and also for sporadic problems with launchctl. Thanks to @xvolks for merging the iBooks (sandbox) fix from @comex’s github into the overall corona untether from @pod2g! As usual, you can choose to install the fix either by re-running redsn0w over your existing jailbreak (de-select Cydia if you do that), or by installing the corona package from Cydia (it’s the same set of files no matter which way you choose).”
The blog post also rendered the readers a tip that when auto-detection fails and tells you that no identifying data was found, one can always select the appropriate 5.0.1 IPSW using “Extras->Select IPSW”.
However, if you’ve already jailbroken your iOS device using Redns0w 0.9.10 then the easiest method is to install the Corona iOS 5.0.1 Untether 1.0-5 from Cydia.
The b2 version of redsn0w includes the fix for launchctl-related issues. One can rerun the redsn0w in jailbreak mode over your existing 5.0.1 jailbreak (even a PwnageTool one), making sure to de-select “Install Cydia” if you do. Always be sure to do a controlled “slide to power off” shutdown of your device before running redsn0w.
The b3 version, on the other hand, fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).
