Hello, I new on this forums, and I am a complete newbie about firmwire and stuff.

I just got a new mobile phone, Sony Ericsson k608i to be precise. Unfortunately it has to be debranded. So I was hoping you can help me.
How to do it? What programs do I need? Please help me, because I don't want those stupid pink T-zones stuff and locked images and that damn annoying T-mobile jingles.

Can you please help me? Please?
