What does the icon 1X mean on Samsung your Shot cell phone?

It means what network youre on for data, for example, if your in high speed area, you will see EV or 3G, if you are in a 1x area, it means you are in an area where your data speed is comparable to dial up.----i work at a major cell phone carrier. Rural areas are generally 1x, but soon hopefully the whole counrty will be at 3G or EVDO speed!!
