Hi all my iphone 4 is on the above subject version and works well with evasion jailbreak. I am just about to get another phone for my mum and it is on 4.3.4 or something round about there, how would I update it to the same as above without installing the new version of update, I do believe the 1 above is the furthest we can go at the moment for a full evasion jailbreak, can someone advise me on what I should do for the next steps ?
