    cant receive or make calls as it says call failed with beeps, i tried searching this problem in the community but i havent seen relevant answers.
    i tried removing the sim card tray reposition my sim card, tried a soft reset (holding the home and switch off button), my phone is not on airplane mode.....
    though if i switch on and off the airplane mode my phone can make calls but after a few mins its back to the same state. it looks to me like a bug or something as i have even tried restoring the network settings from the settings menu. have not jailbroken. had some problems twice earlier this year so i got a refurbished set. cant return the phone to my carrier as well as im overseas now..........

    using iphone 4 ios 5 (probably its some bug with this new update.....not sure though.....)
    pls help thank you in advance.
    iPhone 4, iOS 5

    Plug it into iTunes then do a Backup & Restore.
