i bought an iphone yesterday and my cousin unlock it for me. when i got home, i accidently update to FW 1.1.1 .

I was trying to reinstall back to 1.0.2 but not success.

Now only thing appear on the phone screen is the CD with a USB cable. and it wont go back to the screen that said valid simcar.

i even try to do the restore on Itune with the FW 1.1.1 but it keep said error while file extracting.
what should i do now?

getting a new one fast before the store replacing with all the iphone 1.1.1
or wait for the hack update solution? ( i dont even know if the phone is usable???)
