Thread: iPhone 4 occasional no service

  1. #1
    Default iPhone 4 occasional no service
    I have an iPhone 4 running 4.3.1 unlocked and jail broken. I have an occasional no service problem which occurs intermittently, sometimes never in a day to 10 times a day.
    Is it an unlock problem or some other problem. How to fix it.

    I think this is probably a network issue. Have u tried uninstalling and reinstalling ultrasnow? U may also want to reset network under settings after installing ultrasnow. Mk sure u don't erase all settings as that will brick ur phone and force u to upgrade to an iOS that comes with a baseband that can't be unlocked. Good luck

    It is unlocked with ultrasnow 1.2.2 and there is an update to it with version 1.2.5. I am scared of upgrading gearing losing the unlock in the process. I hate going through the process of restore, jailbreak and unlock.
    Also I have noticed that whenever I make a call, I lose the cellular GPRS service for some time.
    Lately, when I turn of the cellular data GPRS, it doesn't show no service.

    I don't think upgrading to the latest ultrasnow will cause u to lose ur unlock. Try resetting your network settings and see if that helps. I have a few friends with the 01.59 baseband and none has ever complained about a gps issue. I unlocked all their phones for them and had to reset the network settings after installing ultrasnow for everything to work properly

    Ultrasn0w updates are safe, wouldn't be any good if you lose an unlock just for updating it LOL.

    You're network service problems are probably due to the fact that you haven't updated it. Try updating it.

    like what af4s said, remove your older version of ultrasn0w and upgrade to 1.25
