I did this jailbreak about 2 weeks ago when it first came out for firmware 4.2.1 and it wouldn't let me get installous. I'm thinking its a bug in it, because its the newest jailbreak, but that was a real big problem for me. I took the jailbreak off of my iPod now. I'm hoping that this bug will be fixed. Does anyone else have this problem?

I have Installous, and is now fixed. I jailbroke my iPod Touch 3G the day the Windows Jailbreak for 4.2.1 came out. Try it out now, it should work.

how safe is this jailbreak and will it slow down my ipod?

Mar 2, 2011. 5:03 PMChibichuba (author) says:

It is very safe, there is a very low chance that it may not allow your iPod to connect to the computer, but that is a 1 out of 1000 chance that that may happen. It might slow down your iPod, depending on how many GB's it is. But there is an app called Speed Intensifier, which speeds up your iPod greatly.

my ipod is 8g's will that slow it down

Only if you install Winterboard, and load it up with Cydia apps. but then again, you could always download Speed Intensifier.

that doesnt always work though. remember that the more tweaks and apps you have running at the same time, the less amount of free ram will be available.
