My Nokia 5125 has served me well for many years, but I have finally made the switch from TDMA to GSM. (Yes, I know all of you foreigners will laugh at how dated our cell phone technology is )
I really will miss that old brick, but the Samsung X495 at least gets me good reception as well. It'll take me a while to get used to the size though (and the new features. What's that you say, phones have color screens now? ).

Yes, feel free to laugh all you like.
