I bought a 3GS and to my surprise the seller already had Cydia on there. So it looks like I just need to proceed unlocking the phone. But reading about so many different software unlock options on the internet, I'm a little confused as which unlocking software I should go for. I didn't want to rush it and mess something up, so I thought I'd ask here. Should I use Ultrasnow and is there a specific version I should use? Or what software is best for iOS 4.1 with baseband 6.15.00? Better yet, is there a website that shows you which software to use for each iphone Model/OS/Baseband?
