3gs stuck on 4.2 software :(
Hi guys,found this site whilst googling.
basically i have purchased a brand new 4 month old 3gs 8gb but is locked on Orange and on the 4.2.1 update to which the buyer never told me about (just said 4 month old etc). Is it possible to downgrade it,if so how do you do it step by step?
I have read and seen on youtube and googling on forums you can,i download the 4.0.2 software that it should have been on and when connected to itunes and hold shift and click restore,nothing shows up.i cant find the ipsw file.Even tho i rename it at the end .ipsw as told to just nothing shows up whereas when i see it done on youtube the file is there
Does anyone know wether there will be a unthered unlocking jailbrake for it,if so i may aswell wait rather than try sell it on and buy one on 02.
Cheers for help and any replies
