(I have an iPhone 4 (not 4s.
I downloaded Firmware:
iPhone 4 (GSM): 6.0.1 (That's the one my iPhone is updated to) (Btw, my iPhone is T-Mobile because it's unlocked)
I downloaded RedSn0w:
RedSn0w 0.9.15 beta 3 for Windows.
So the issue is is when I try to click the IPSW thingy, the step you do after you click extras and then 'Select IPSW', It says that the IPSW is not supported by that version of RedSn0w.
Btw the file name to the ipsw I downloaded is: iPhone3, 1_6.0.1_10A523_Restore
Can someone please help me out? Please? :/
(Please only experienced Jailbreakers. I'm a noob at this. And please nobody saying 'You shouldn't jailbreak it or anything'.
