IOS 4 V 3.1.3 Jailbreak Ok all, i am currently on 3.1.3 Spirit JB on Itouch 64GB, i am not sure if i should upgrade to IOS 4 and jailbreak on that. I am kind of confused as to where we are with apps being compatible for this IOS 4 JB, i know people say oh they are all fine and others are saying well actually they arent! Am i better off staying on 3.1.3 with an Itouch as most of the features require the Iphone 4, or should i upgrade? I am just interested to find out what peoples opinions / personal experiences with this is. Cheers!
