I have an I phone 4 it's jailbroken and unlocked , I used the sim cutter to cut my sim and when I put it in it says Invalid Sim or it shows signal but it doesn't show a carrier . I bought the sim card today btw , Does anyone know what I can do to fix this ??
 
try powering off then on again...if that does not work try uninstalling ultrasn0w and then re-install ultrasn0w again

I have tried turning the power on and off , like right now I did it It shows phone signal but no carrier , re installed it and it shows the phone signal again but no carrier
 
A couple days after 4.2 is released.

Sometimes it takes much longer. I wouldn't assume it will be released so quickly.
Thank you so much , when the update for the base does come out will Cydia have it or do I have to download it somewhere?

You will have to update the phone though software like Pwnage tool to preserve the baseband and the unlock.
