It happened to me for the first (and so far only) time, a couple of weeks ago. But I've only had my Treo 300 for a few months.
I thought that Sprint's tower must have gone down. But then I turned on my old Sprint phone, and it showed 4 bars. So then I thought that my Treo had died completely. I was waiting on hold with Sprint customer service when it finally occurred to me to try a PalmPilot soft reset on it. Presto, it worked again, and has been working ever since.
