There is an iphone 3gs 4.1 iOS (06.15.00), it has Cydia and ultrasn0w (so I assume its locked to a network, and I assume its on ipad baseband right?), the question is: Can I update iOS to 6.0? As I was told before (much much before) that you cant (or its better not to) update 3gs phones with ipad baseband? Wont I loose jailbreak/unlock if I update to 6.0? Which tools to use for the unlock? Any specific information I need to do this? Or can I just use redsn0w and jailbreak and then write ultrasn0w and unlock it? Thanks!
