I see that a couple of you have successfuly patch-unlocked AT&T W580i's so I will ask here.

I tried the Simox method.. and although the process seemed to go smoothly.. no errors or "failed" messages, the phone's still not recognizing a T-Mobile sim.

I used W580_R8BE001_MAIN_GENERIC_LA_RED52.mbn to generate the quick access and unlock patches, and I have W580_R8BE001_FS_AMERICA_2_RED52.fbn &
W580_CDA102568_107_R8A_GENERIC_AMERICA_2 on my phone.

So I don't think the file combination is the problem, as some other ppl have said to others with this problem. All 5 padlocks are open in the Simlock menu. The phone seems to function fine after the process, other than the fact that it isn't truly unlocked.

Any thoughts?

Thanks all!!!:)
