Hi,
I wanted to let you all know that this is working 100 %!!
After a very long 2 days!! of reading every post on the net and try all the methods in the world, I started to do every step that is on this page. I even went before this and got a new sim card from AT&T. I had the phone since it came out and I decided to use AnySim to unlock my phone, I don't know why

, but it didnt work and I had to restore.
I then had no problem with my phone and I had the version 1.0.2 on it and use iBrickr and all that good stuff. I decided then, I don't know why again

, to try to upgrade to 1.1.1, because I was thinknig that my phone wasn't unlocked since the stupid AnySim didn't finish the job. Well, guess what, my phone was a brick after the restore and update by iTunes!!!
To make a story short to everyone that has any questions, use this page and I am sure u will get your phone back on track!
Thank you all that helped and to everyone involved in making this a easier way to return the phone in a working mod.
I used:
Windows Vista
iTunes ver. 7.4.3.1
iBrickr 0.91 and all the pack that is recomended on this forum on this page
iPhone 8GB vers. 1.0.2 - bricked and the upgraded to 1.1.1 and moved down to 1.0.2
Downgrade the simband and modem!! with Erica's Unlock
MY PHONE WORKS NOW!!!! THANK YOU!
