Question about k810i firmware for use on T-Mobile network

[Libertine]

I somehow posted the wrong firmware! :rolleyes: I edited my original post to reflect the correct firmware i used.

Two questions:
1.) Firmwares are completely locked? I thought they were locked to a specific network.

2.) Since the firmware says T-mobile on it, does that mean T-Mobile can unlock it through an IMEI #?

Thanks for any help and please understand, im completely new to this wide world of phone modification.

Wotan server has not responded to me in a week, so im guessing that tells you what they care about.
