Do I need to unlock my phone.

[co4nd]

I've got an off contract iPhone 3GS from AT&T. I'm going to get a sim from H2O to use this phone as a pay per use phone for the kids. do i need to unlock the phone before swapping SIMs?

Thanks,

If you can get the phone unlocked it never hurts to have it unlocked for what you want to do.

So are you saying I should but I don't necessarily have to? What does unlocking do for me?

thanks
