i have a huge problem!!!
my iphone 4 was jailbroken for t-mobile then i didn't know and upgraded to 4.0.2 and now i can't use it anymore. is there a way i can downgrade it or perhaps just jailbreak it again??? HELPPP what to do????
nope, you have to wait a little while like maybe a week or 2, because apple stopped signing the 4.0.1 firmware, so you cant downgrade. i said you might have to wait a couple of weeks because 4.1 comes out today (supposed to) and they said they had a jailbreak going for that one. so after the JB comes out just use ultrasnow again to unlock your phone
