Re: Cingular and MediaNET / data service... I decided a couple months ago that I wanted a Treo 650. My choices were therefore Cingular whom, by way of AT&T I had been a customer for 2+ years with, or Sprint. So I rolled into my Cingular store and asked what they could do for me. I had heard MediaNET was $20/mo, which seemed reasonable. Turns out, as you alluded to, they charge extra for "devices which are primarily data devices" or somesuch, and if I wanted unlimited data on a Treo, it was $80/mo. Yes, $80. Sprint, on the other hand, for what is now the same speed of service (but will soon be a bit slower due to Cingular upgrades, allegedly) offers unlimitee data for $15/mo, or $10 if you're skillful with the CS reps. Cingular lost me as a customer faster than you can say "raising the bar." Couldn't be happier with the Sprint voice or data service, either.
