So I went back to the iPhone (3gs) and I I tried jailbreakig it by using pw age tool on mac and sn0w breeze on win 7 on my mbp using vmware. I always get stuck on dfu with sb and with pwnage tool it won't go into dfu. Yes I checked the serial # on the iPhone. It's not a mc model so I should be able to jail break. I won't go to blackra1n. (I don't like that every time I reboot or shut off my phone o lose my jb and have to make it rain again). So what can I do? Is there a way to stop my iPhone from resetting the spring board while using blackra1n? Or shall I try another method of jailbreaking. Btw I'm running 3.1.3 and I'm not sure what to do.
