I have waited a LONG time for an untethered jailbreak for IOS 5, and it seem this was released in December 2011.
Sadly I need to jailbreak my iPhone in order to run certain programs not approved by Apple, it is sad that people do not get to choose what they want to install on my iPhone but have to rely on what the Steve Jobs mob think is good for them.
Well anyhow, now you can jailbreak it and choose yourself 🙂 I’ll have to get around to doing this sometime soon, but as mine is already jailbroken it seem there is some work in this, but with a version of 4.2 (as I recall) it is about time 🙂 hope it will speed the thing up a bit also, it seem to have become a bit sluggish over time :-/
