Ok here everything I did. I had my father buy me a factory unlocked iPhone 4 from the UAE. He bought it and used it for a few weeks with no problem in Kuwait. When he brought it to India , I checked the firmware and base band . It was iOS 4.0.2 with 1.59.00
I wanted iOS 4.1 so I could jailbreak it. What I didn't know was I could update the firmware with no problems as it was a factory unlocked phone.*
So I preserved the Base band using tiny umbrella and updated to iOS 4.1.*
But the phone showed the insert sim thing. When I inserted the sim my dad used to use it didn't work. So I had to hacktivate then and use ultras0w. My question is: if I revert to iOS 4.0.2 or restore to iOS 4.2.1 will I have to unlock using ultrasn0w
And
Why wasn't the sim accepted. Will it accept if it had the proper base band version? Pls I need help n
