I am currently using Firmware 3.0 and I have no experience what so ever Jailbreaking or Unlocking iPhones. I'm good with computers but this I haven't learned yet. What I need is a very very detailed explanation on how to Unlock and Jailbreak my iPhone. I'm using T-mobile so If I mess up then I will not be able to talk on my phone. Please give me an accurate explanation on how to do this or link me to a video that is very accurate and shows step by step how to do this. Thank you.
