Windows Mobile Professional

Hey everyone, now this thread is for the best of the best techies that know it all. this I find to be a big comparison on a lot of different ends. I'm wondering about these two phones and how they compare, as opposed to call quality, internet quality. Here's what I know and heard so far. EV-DO is much much faster than EDGE Technology, but I heard so much about Verizon's EV-DO compare to cingular's edge as opposed to Sprint's. This is probably dumb but it probably is the same or maybe it's not. Tell me your feedback on every little detail because there's a big difference in plans as well. Sprint charges only $15 for unlimited web data, and Cingular charges a whopping $39.99. Well, here goes nothing hope it becomes a hot thread with many opinions.
