MFI Question

[gary100]

Hi Everyone,
i have a question regarding MFI Multiloader which can unlock blackberries.

Do companies like AT&T use MFi when you ask them for an unlock code or do they use other software. If they do use other software, does anyone know the name.
I'm just curious.

Thanks.

The networks are provided the unlock codes within 3 months of having the phones delivered.

Networks don't need to use code generators or unlocking servers

Thank you. That explains it why they do it over the air.
