So I have a 2G iphone that I jailbroke it on 3.0.1 using Redsn0w. I'm thinking about updating it to 3.1.2 using PwnageTool because I already have it on my mac and because I recently JB my friends to 3.1.2 using it. I'm just not sure if it's worth it... My question is how many of you have updated your jailbreak and are you happy with it or do you suggest I stay at 3.0.1?
