I'm currently in search for these files.
W580_R7AC001_CINGULAR_CID52.mcu.rar
W580_R7AC001_FS_CINGULAR_CID52.dec.rar
CDA102774102_W580_AT_and_T_US_CINGULAR.cus.rar
currently there is only 3 firmwares with applicable CDA on file at TopSony DL.
I think the above posted files would be a worthy addition to the firmware/cda list for the w580i.
These files would give us AT&T and Cingular branded users a full backup to flash to if need be. provided we previously backed up or GDFS prior to flashing firmware changes.
Only place/site I have located these files are on a MT-Box support site.
anyone with any info or files would be greatly appriciated.
