iOS5 Beta 5 finally gets jailbroken, of course this isn’t a full jailbreak rather a “tethered” jailbreak meant for jailbroken app developers. For all of you interested in early-adoption of the jailbreak, check out the Dev Team Blog.
THIS IS A TETHERED JAILBREAK ONLY! No new exploits are being exposed with this jailbreak (it uses geohot’s limera1n bootrom exploit), but that comes at a cost. You will need to use redsn0w to “Just boot tethered now” to be able to use many things, including Cydia and Safari. If you see a white icon for Cydia, or if Cydia or Safari crash when you open them, it’s because you didn’t boot tethered.
