Okay I got an iphone 3 but I am with t-mobile so I planned on unlocking my phone. When I first plugged in my cpu my computer upgraded my phones firmware to 4.2.1 automatically and my phone updated its data...Now I was unaware and began to jailbreak and unlock my phone with redsnow 9.5 it worked but I noticed something was wrong so I looked into it and found that the iOS was newer so I needed to use a different version of redsn0w which I did. When I used it I change my baseband to 6.15.00 so my phone would unlock but instead the process caused my phone to brick. I cant take it to at&t because 6.15.00 ends all warrenties and I'm not a wireless user for them. I tried Quickpwn but it doesnt seem to work and tiny umbrella is MIA for 4.2.1 of iphone. I cant restore to itunes because of the fact that its 6.15.00 and it will not take and everytime I try I get an error code of 1002. Can someone please help?
