Hi. I just jailbroke my iPhone 3G to 4.0. I then unlocked it with ultrasn0w. Someone told me earlier that if I used redsn0w then push would work no problem but it seems like it is not working. Is there a push fix for 4.0 yet? I heard there is push doctor. Dunno if that will work. Has anyone given that one a try yet? Please let me know!
