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.

I'm so stupid doing this in the far future. I got greenp0sion and I try, Try, TRY again it does go in dfu mode. So any help or am I screwed?

It doesn't go in dfu I meant sorry.

When I try to install it, it says "Product configuration is missing!"

I try to go to www.greenpois0n.com , yet internet is telling me the page no longer exists... SOMEONE PLZ HELP! I have an ipod that i want to add other apps on, but all i have is music, and i have had this ipod for 6 years now, with only music on it...

It worked... Deym...

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

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
