Hello everyone, I want to Jailbrake (with Redsnow) and Unlock (with Ultrasnow) Iphone 3GS iOS 6.1.3 with serial number 8720519xxxx, Firmware 05.16.08 . Clear warning on Redsnow beside "Install Ipad Baseband" say that I shouldn't do it because I could make damage to the phone (because production date is after 34th week of 2011). I guess that point is to make firmware unlockable by upgrade it to supported by Ultrasnow. Other action I can do it to check "Downgrade from Ipad baseband" in Redsnow menu. Should I do it or can anyone please advice me what should I do. Thanks a lot in advance!
