I went through the jailbreak process and when I went into cydia to add ultrasn0w it wouldn't add the source. I think it's because I am on IOS 5.0.1 and don't have baseband of 6.15.00. Unable to see how to upgrade my baseband so I can complete (if that's all that I need to do). No phone or texting since last night, soo hoping someone can help! Thank you for your time!
