hello can someone help me please here's my situation: i just bought an used 3gs 3.1.3 (950 in sn so new bootrom i guess) with jailbreak and unlock i didn't plan to update the firmware at all i just wanted to delete the pics and apps and music on it. so i did a reset from settings->general (f'in bad idea..) it froze during the process now it gets stuck on the apple logo after the spinning circle appears. tried irecovery but it didn't help. it is possible to fix it? it is possible to reinstall 3.1.3 or 4.0.1 or only 4.1? it is possible to install them without upgrading the baseband (seen some tutorials using umbrella)? i saved some shsh blobs with umbrella before i reset it but ofcourse they are for 4.1 (4.0 are no longer apple signed) if someone explains this i would greatly appreciate..
