Folks, I've spent money with three different unlocking providers, and now pursuing refunds from them all (CID 52 is screwing it all up). If you have an AT&T branded W580i, just give AT&T a call and ask them to unlock your phone. I have TMobile and bought my W580i from Ebay last week.
AT&T will ask you for contact info, the IMEI, and it takes about a week for them to get back to you (so they say) though I hope it is sooner than that. They will provide the unlock code via email or phone.
Oh yeah, and the kicker..... it's FREE! :eek:
Now, once that is done, I look forward to de-branding the $#!^ out of it and hopefully getting my refunds back.
