Well I haven't noticed this... I guess I can say 95% of the time when I make or receive a call is without issues. The other 5% is for tower issues, low reception, etc.

This would most likely be a tower issue as Sprint tech support said. I wouldn't use the argument that another phone works since that phone may have a better signal, even if at the same place phones may act differently.

If you can prove the pattern happening the same with different phones (same model/make of course) and in different areas, then I'd definarely involve Sprint AND Palm to check if anything else is uncovered.

I will keep an eye out for this happening though...

Any similarities as far as hacks, apps installed, etc.?
