iphone 4 just announced.

[goalie204]

well, i have 4.1 jailbroken and have the ultrasn0w carrier unlock. Today i spent 15 bux on a pre-paid sim from At&t, cut it to micro-sim size, popped it in, and it didn't work.

I don't know if i cut it improperly or if my phone isn't "really" unlocked, and i don't know how to tell.

I am currently in america using my canadian phone which is why i was trying this.
