Right, but we also know that GSM coverage in the US is incredibly crappy (only a handful of the very largest cities), so this is basically worthless anyway. If you want to be able to get coverage most anywhere in the world, you have to have 1800/900Mhz GSM for Europe and Asia (there are plenty of places in Europe where the 900Mhz networks don't have coverage or are saturated, and the only way you'll get coverage is by having 1800Mhz as well), and then you need AMPS/NAMPS plus either TDMA or CDMA to get coverage for the US. And you just have to hope that your carrier has sufficient roaming agreements with the other carriers for wherever you might go. -- These are my opinions -- not to be taken as official Skynet policy ====================================================================== Brad Knowles, To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
