    my phone is blackberry curve 8320 (vodafone).And it is unlocked.when i keep my phone for a while ..may be hours..it can't get any signal and says ''sim card error''.only way to make it work is to turn it off and turn on again.its really weired. how do i solve this? Is it because of outdated device software. if upgrading the device software is the solution then will it make my phone locked to a specific carrier?coz i don't want my phone locked. pliz help me!

    device software version:v4.5.0.42(platform 2.7.0.60)
