...using prepaid iStream data service from VoiceStream [T-Mobile US]; it's not bad, coming from a guy who until recently used dial-up Internet access. (I only get GPRS/EDGE service indoors, but it's a helluva lot faster than dial-up: 16.8-26.4 Kbps v 56-237 Kbps, with comparable latency (25-1000 ms)...go figure) hey, I'll take what I can get around here...
