Unlocking Iphone 3gs

[kfoshee335]

I'm new at this so please bare with me. I have an AT&T IPhone 3GS which I am using on their gophone plan. I want to use it on T-mobiles prepay but it's not unlocked or jail broken. I don't have a computer or access to a pc so I'm want to know is there a way I can unlock my phone without using a computer?

No, you need a computer to both jailbreak and to install the iPad baseband(in order to unlock).
