I'm new to iphone and then to jb
I have an iphone 4 (4.2.1), I did a tethered JB using redsn0w 0.9.6b4.
I have seen that there's more recent version of redsn0w (0.9.6rc8 for Windows) and 0.9.7... for Mac.
Do I have to jailbreak again with new version?
What would I gain then?
And if yes, how do I?
- just re - jb?
- restore org ipsw then re jb?
Thanks a lot
