I tend to keep the same cell phone 3 to 6 years. I think I'm due for a new one now, since just about everyone says that they hear static from my phone. I've dropped it too many times and there's a few cracks in it. I have a Samsung r225m which I got at the end of 2000 with T-Mobile. Right now I'm debating whether to keep T-Mobile or switch to another company.....
