Debranding a Sony Ericsson Vivaz U5i that's already been flashed with Wotan server?

Hello,

I recently flashed my Song Ericsson Vivaz U5i and my 3 network SIM still isn't valid inside my T-mobile phone, I'm a complete noob. I was wondering if you could direct my to a tut that actually DEBRANDS the phone so that I don't have to call T-mobile to have it unlocked by them? So that I can use a different SIM inside the phone?

Thanks.

You can't unlock phone with flashing.Flashing and unlocking are 2 different things.Take the phone to some private unlock/repair shop.
