3G TurboSim Settings?!

Hello,

I just want to collect more info on how to set up the turbosim. I have the 3G on 2.0.2. I went the other day and purchased the turbo SIM to find out that it didn't unlock my phone, when i asked back i found out that it is gonna cost me in addition about around $150 to unlock and i should keep the phone with the shop guy for like 3 days because some kind of settings should be applied to the SIM to make the unlock (and not only cutting edges, am talking about serials or digits) - at least that's what the guy said


So any idea? can i have an online tutorial to learn more about it?

thanks

My 3G was purchase on Ebay, it comes with a Turbo sim.....
i am not sure if the settings was change before it was shipped, but all i did was to installed my sim with the turbo sim, setup my cellular data network, APN settings and i am good to go.
