[QUOTE=simox;75654]What message do you get exactly?

"Insert Sim or Press Demo" which is the same msg a 580i gives when there's no SIM in it at all.

It looks like the phone is unlocked successfully. Have you tried the T-Mobile SIM with other phone, or another SIM with your phone?

Yes, that's what puzzled me. It appeared on the phone itself, that it was unlocked. But the T-Mobile SIM works fine in a code-unlocked W810i, and a RAZR. The AT&T SIM still works fine in my phone, so it's not a bad SIM, or a faulty SIM slot. Now I'm really puzzled.

Here's the log if that'll help.
