I get my phone bricked. I have a 1.1.1 firmware, so I used this method to downgrade the phone, and use the Erica's unlock method to unlock it. Every works as described. However, it won't pick up my tmobile tzone setting no matter what I did. The EDGE setting will change back to cingular... after the phone is restarted, so the data part is not working. The voice and wifi part works with no problem.
So, I decide to apply the phase 2 again to put it back to the virgin state and use iUnlock to unlock the phone. That also works fine and tmobile works after that.
Then, I decide to go to 1.1.1 in order to apply AnySim 1.1.1. Before I did that, I used the phase 2 to virginize the phone again. Now, I got f..k.

The phone now has invalid SIM error after I virginized it again. I also noticed the IMEI is changed to something that is not valid when a SIM card is in the phone during boot up.
Any suggestion to fix this mess.
