The iPhone Dev Team has released a new untethered jailbreak solution for beta testers. The new download comes with a couple of improvements. Firstly, Bluetooth – which was disabled in the jailbreak software until now, has now been enabled. Also, the Dev Team has noted that any sandbox related issues must be fixed in the new version.
While this version is closer to a public release (you may recall that the Dev team had indicated that if beta 4 goes well, the next version could be a public release), it is still advisable to go ahead with this download only if you have already tested the older beta versions. Interestingly, a basic version of Redsn0w for Windows too is apparently available although the Dev Team points out that this version is very slow at this point. A test release should be out when the Dev Team manages to speed this up.
