I'm using an EV-DO modem here in Guatemala, but I see that the ping times are ~200-400ms to the ISPs machines (i.e., the first hop is most of the time). Some people are a bit less (say ~100-200ms). Is this normal, or is the ISP screwed up (as usual)?

There are however times on the Sprint network that the bandwidth is reduced, or the bandwidth is zero, because it can't connect to anything because the network is so busy. WIth Sprint's CDMA 1xRTT network, voice and data share the same network, but voice is the bread and butter of the business, so it will get priority over data. This is why I'm saying, EV-DO (and later EV-DV) will do great things for VoIP over cellular networks. EV-DO (DO stands for Data Only), dedicates a high speed data network, more available bandwidth for everybody, and less latency, hence less jitter. I'm excited to see these developments, as I believe it will make VoIP more reliable over these types of networks. At the moment, there are simply too many variables to trust it.
