Hi, I am in Canada, wanting to use a Locked AT&T iphone. When I initially bought this over kijiji , the seller unlocked it for me . By mistake it got updated with itunes and now its back in the USB-Itunes Logo. I have tried black raining it, and it gives me message that it has rained but it does not boot the phone, its stuck in waiting to reboot on blackrain. Right now, its on the usb-itunes logo. I have tried redsnowing too but its looking for a right .ipsw file and I have downloaded over 10 diff ones but none are working. I remember that it was on 3.1.2 version (still not sure of the version) Any help from Pro's???
