Is my iphone 4 locked or unlocked?

I have a iphone 4 that had att service, I never paid the bill and after 2 months the "at&t" sign in the top left of my phone screen switched to "no service". If I want to sell the phone does this mean it's locked or unlocked?

No, its still locked to at&t. You just arent getting service because you didn't pay the bill.

No it is not unlock. Your iPhone 4 is still unlock with ATT. You can have it iPhone Factory Unlock for you or the next owner will be able to use it to other carrier.

It's locked because you didn't pay your bill nobody will be able to use the phone for ringing or texting people the phone is just like an iPod now

  • Why does my unlocked iPhone 3GS stay locked? I jailbroke it with redsnow, unlocked it with Ultrasnow a million times over and it remains locked. Using baseband version 05.13.04 with 5.1.1 iOS. Calls and text work fine, but no data, no matter what. Use Wi-Fi in my house, but that's all i can use. I've spent a week doing this over and over and nothing seems to work. Tried dozens of videos online, countless blogs and i followed every, single step x amount of times. Using straight talk right now, should I try T-mobile maybe?
