iPhone Dev Team has launched Redsn0w 0.9.9 b7 for faster jailbreaking of iOS 5 on iPhone 4 . Redsnow 0.9.9 b7 which supports both Mac and Windows operating system now reduces the time of jailbreaking from 210 seconds to 80 seconds , making it 60% faster .
Redsn0w will no longer “stash” the applications by default during the jailbreak . However this will increase the first time loading of Cydia after jailbreak, during which the stashing of applications will occur . You will get the option under Redsn0w preferences which will allow you to choose whether you want Redsn0w or Cydia to stash applications.
