check it unlocked or not... go to Option>Advanced Options>Simcard>
type "MEPD" and check there all r desabled
if the network is active .. u need to unlcok it.(contact me if locked.. i will give the code free)
in blackberry if u unlock it,.. it will not lock again if u upgrade or downgrade
updating the OS will not relock a phone.
make sure you go to a reputable unlocker, and upgrading or downgrading the OS will not re lock the phone/
Might be damaged sim contacts ,,,
I agree with the others, re-installing OS will not re-lock your Blackberry.
But, if none of the sim cards are working with your device maybe it's a physical issue with the sim slot...
