I've had the 3GS with 4.3 firmware previously and have unlocked it by installing the iPad baseband and jailbroken it as well. Now I read about upgrading to iOS 5 and it said if you do it won't be unlocked anymore and the baseband will not be preserved. I was fine with this because I want to sell the phone to someone who is with the service provider that the phone was originally intended for.
However when I upgraded to iOS 5, I can't even activate the phone with the SIM card of the service provider that the phone is intended for. I know this SIM is legit and works on other phones but it won't activate on this 3GS.
What's wrong?
Thanks
