Hi! I have a 3gs 3.1.3 bb 05.12.01 with jailbreak and unlock (dont know if it is old/new bootroom)... I want to upgrade to IOS 4.1!! I already have Pwnagetool to make my custom firmware (4.1) but I read I need to have my SHSH for 4.1 saved in order to pwnage and keep my baseband.. The problem is I use tinyumbrella and this appeared at the end... 12/27/2010 11:00:04.307 CYDIA DOES NOT HAVE YOUR SHSH FOR iPhone3GS 4.1 (8B117) THERE IS NO WAY FOR YOU TO GET THEM. SORRY. YOU ARE JUST TOO LATE. Can someone help me please?? Does this means I cant upgrade to 4.1? do I have to upgrade to 4.1.2? What can I do? THANKS!!
