Hi there everybody. So I have a untethered jailbroken iphone 3gs on ios 5.0.1. I need a phone to use so I'm thinking about upgrading my baseband to the 06.15.00 baseband that way I can unlock. I don't really mind losing my GPS since my GPS doesn't work at all anyways. So since I don't have the SHSH blobs saved for 5.0.1, I can't restore it and just jailbreak and upgrade the baseband simultaneously so I was wondering if I could just upgrade the baseband and preserve everything else in my phone of if I have to lose my untethered jailbreak and go to ios 5.1. Thanks for reading all that.
