I recently bought a used virgin iPhone 3gs, with original 3.1 firmware. I have been researching online, looking for the best CURRENT jailbreak and unlock solution and am getting a little lost. The phone has 5.11.07 and I believe it's from 2009 week 37, which if I understand correctly, gives me a choice of untethered jailbreaks from either RedSn0w or Pwnage Tools, or BlackRa1n, (which I'm hesitant to try, due to it once destroying the baseband on another phone). I have both Windows 7 and Mac OSX available, so I was thinking about using Pwnage to get it up to 3.12 with a custom ipsw, then using Ultrasn0w to unlock through Cydia, but I'm open to other suggestions. I plan to store blobs and eventually go to the newest firmware possible (with Tiny Umbrella?) while preserving my baseband, but for now, older is fine. I looked at some posts on the forum here, and it seems like all the 3.1 posts are pretty outdated. Before I get started, I just want to make sure I'm not overlooking any jb/unlock options that might be easier or safer, or newer. Any thoughts?
