I have a RM-75 (6030b) that I had bought on the road to replace a dead phone. I want to change the frimware to either a generic Nokia, or Cingular. Right now it is Tmobile (I already unlocked it). I have been searching the net for 2 days now, and can't find what I'm looking for. Can anybody put me in the right dirrection or perhaps PM me some answers? Thanks
