3g iphone can't call or recieve calls after update

[hello0123]

Hello, I upgraded the iphone 3G to iOS4 and jailbroke it to pass through the SIM SUPPORT error, although after the update, my phone cannot call nor recieve calls, does anyone know how to fix this problem? Thanks

BTW: The phone was jailbroken with redsn0w, thanks

Try to reset the Network Settings, it might help.

Try this solution, found it and several people said that they solved it so I posted it for anyone to use it in case they might need it:

yes, but does this correspond with the current firmware of the new update?
