I bought my IP8 from att.com on preorder, paying the full price. Today I tried the unlock procedure and got the following message below. The IMEI number I got from Setting/General/About is the same number that I get from entering *#06# "The IMEI you entered does not appear to be an AT&T wireless phone or tablet. Please re-enter the correct 15-digit IMEI number for your AT&T wireless phone or tablet. You can obtain the IMEI number from the wireless phone by dialing *#06#." I should note that when I received this phone, I had problems activating it. Since I wanted to use it immediately, I just switched the sim card from my previous phone and from that point on, it worked fine. By doing this, did I in effect make this new phone a non sim phone with ATT assuming I still was using my previous phone and this one is not activated? My reason for wanting to unlock this phone is that I’m considering ordering the X to replace this phone, which I may then want to sell. I would like to know what the status of this phone is before I trot into my local ATT store to ask them.
