do not update!!! there is no jb for 4.3 if u do update u hav to wait for the 4.3 jb to be released, n it will probably delete everything u downloaded from cydia as of now just click cancel
ive been playing with jb iphones...is jb itouch 4g the same? as in if its not jailbroken and i upgrade i cant downgrade it? or is it like the iphone 3g where blobs dont need to be saved? thanks
Man i would not even update my iphone if it did have a jailbreak alot of people say it has slowed there device and there battery life is very sucky since the update
