So I have a Cingular branded w810 and I want to put in the newest unbranded firmware. My problem is I have no Idea what the newest firmware is, or how to do it without screwing something up. Could someone let me know what files I need and possibly a good tutorial to guide me through the process? My main purpose for this is to use any file I want for my ringtone, as cingular only lets drm mp3's or files under 30 seconds. Any help would be appreciated.
