Sorry to bring it up again - 6620 At&T USA Unlocking

[aracno]

I did search the forum for it, but I couldn't decide which codes are to use, some say "asic2 and asic6", others "asic5 and original", among others...
I have the 3.10 calculator, under NOKIA I should use 6620 or DCT4(expert only)?

My phone will arrive in couple weeks so I am worried about the hardlock, since I live in Brazil and Nokia doens't flash this model here yet.
Any help will be much appreciated

I just recently got a 6620 and i unlocked really easily with the v3.10 unlock calculator. Don't bother going expert or any of that just select 6620 from the nokia list put your imei number in and choose the country and provider. I got it first time doing this i don't know why so many people had problems before.

I still haven't made it.. tried all possibilities, the phone doesn't say "code error", just "insert sim card"...
