Dave: Sorry to jump in, but as PCSTEL might be busy lurking on Yahoo.... ;-) The answer is, like most things, "It depends". From a phone utilization standpoint, the 'time' used in a 'conversation' is small. The requirements of ' voice' use a small percentage of the total available bandwidth over the entire call, so there is a very significant amount of 'non-talk' time that could be used for data. ( I seem to recall seeing some numbers about this ratio, but I have no link.) Additionally, the data packets are not time or sequentially constrained as voice is, so alot can be done in the down times of a voice call. But then, your network has to be 'optimized' to handle this. It is all a trade off. Check out the Qualcomm website. Jeff Vayda

"Pardon my ignorance, but can this phones be used for voice and data simultaneously?" Sorry, for the delay, but the Misses and I were up enjoying the snow in Big Bear yesterday. In effect, I don't think so. Unlike other operators, CricKet does not offer direct (non dial up) data services. And your dial up rates are going to be capped at about 9kbs. Obviously, if you use it for dial up, you can't talk at the same time. So even if 1X offers the availability of 150kbs data rates, if your Service Provider does not offer "Direct Data Services" then you can not access those rates, and would be limited to dial up rates.. In which you still have to have an ISP and pay the associated ISP fees. What 1XEV-DO will allow is the use of Modem Cards in a Laptop, or a Fixed Unit that connects via a USB port. Like those being displayed on ComDev's web site. mergy.net So this allows CricKet to reuse much of it's existing infrastructure and spectrum to and underlying fixed network to provide additional revenue generating business segments. Like Medium Rate Data. I hope that is what you were looking for? Regards, PCSTEL
