The problem is that after jailbreaking and unlocking with ultrasn04, when I put in my Tmobile sim card (which I just put the data plan on), I continue to get the message "This sim card is not support. Hook up to Itunes." Having read around on the internet, it appears I need to activate the Iphone first, then follow the instructions to jailbreak, add unltrasn0w, then use simhelp to remove the locked folder and replace it. Sim help link: (http://www.hackint0sh.org/f204/156937.htm) Now, the problems are. 1. I am not sure if the phone is activated. I can access the menu to jail break it. If it is not, how can I activate it? I have an ATT sim card for use. 2. Even if not activated, when I get all the way through to ultrasn0w and finish installing it, the simhelp program will not recognize the iphone, so I cannot replace the folder. --- On a side note, after I am done with all this, I will be able to call with the phone, text and use the internet? Thank you.
