Download this firmware and install shift restore in dfu mod. When it's finished iTunes should throw up error 1004 don't panic Now you need to exit recovery mode. Click on ‘Kick device out of recovery mode’ in TinyUmbrella or another program.. This firmware is not a custom firmware it's edited from original firmware..Your baseband stay in 01.59.00.. then jailbreak and unlock.. If your iphone4 stay in Apple logo you have to try this.. No facetime error. No network error. No any other errors.. No risk to baseband update.. its simple its like an original http://www.fileserve.com/list/NBTtugZ rar password : tavelli
