    Buying the phone with At&t and cancel or buy it without a contact?

    what firmware are you currently running? you should be able to JB with no sim card...or just insert any sim just to try it

    Put the phone into DFU mode to upgrade to 3.0 in iTunes

    Shut iTunes, put the phone back in DFU and run RedSn0w

    Unlock with UltraSn0w

    help

    my friend gave me his first gen iphone, he got the new one. AT&T wants a butt load of money for a deposit for me to open an account. What are my options people? they ATT guy put a sim in it, and the main screen says all i can do is make an emergency phone call, my friend wiped the phone off before he gave it to me. any suggestions. I am currently a Sprint customer

    ok, i am now able to jailbreak the iphone, but i get another problem. My iphone was not able to receive incoming calls sometimes when it was jailbroke by using pwnage 3.0. Like i need to make couple out calls in order to get my incoming calls successfully, after awhile, the incoming call function not in order again. How should I fix that problem? thx

    How did you do the unlock? Which network are you now on?

    My iphone works perfectly now if i don't sync it with my itune. But if i did sync it with itune for my backup, then the problem exists. I am wondering if there is any virus in the songs I downloaded or the applications i downloaded from Apple store are not compatible with the ultrasnow or redsnow. Any idea?

    Rather than synching from backup then, it would be best to reload things one by one and see if the problem re-occurs. If it does you'll get a better idea of the cause.
