    Default Edge does not work after unlock on 4.1 (iPhone 4 old bootroom)
    Hi

    I have done the jailbreak and unlock perfectly on my iPhone 4 (ios 4.1) but the cellular data does not work after I put the correct APN even.

    It was perfect when I was in IOS 4 and now big problem. Whenever I try to browse then it always shows "Cellular data could not be activated"

    I try several way like creating custom APN from unlockit.co.nz but none of them work. Can anybody help me on this issue.

    Thanks

    Boil your iPhone 2G in 110 degree temperature water to transform it to iPhone 3G S!!

    Same happened to me. Take the sim out and put it back in while your phone is on. Mine worked after that

    Yes, that works, but if you reboot the phone the cellular data sometimes won't work again. You need to pull the sim out and reinsert again. Nobody has been able to explian why that happens to me.

    It is possible the sim csrd is not properly cut.
