Hey all! so i decided to be nice. I'm not an at&t costumer after a bed experience with them, so i'm a t-mobile for now which means i need to unlock the phone. i bought iphone 3g 16gb for my dad's birthday, and it's been the first time after a few days and many iphones that iv'e been jailbroken to friends. it's just not working, i only want to unlock it into simfree. thats it. i tried blackra1n, and pawntool the device was fine, but after i installed ultrasn0w which didn't helped or blackra1n which got the device stock on the apple logo without end, i'm really don't know what to do. my dad't bday is going to be this weekend, and by then i want to be able to do that, it's really important for me. i'll be happy to get some help and tips about it, i know that the iphone got a clean upgrade from itunes to 3.1.3, and i'll be happy to provide any detail. thanks alot! Roy.
