WHOAH There buddy.
ROMS are really dependant on the user and the programs that they are using.
If you want an official cingular rom, look for the ones with Cingular as the retailer. the benefit of these is all your data, mms settings and such are all done for you, the bad is they are loaded with all sorts of crap and are slow. If you want something a little different then take a look around from one of our cooked roms, each has its own falvors and options you are just gonna have to read and stop being so demanding.
