Yes you can ..
you can "dial up" to your isp and you get the speeds you mention .. <VIA something called CSD and yes its slow.. >
but.. there is another way .. a better , faster way .
you do it using the data side of your phone..
this side connects not thru a telephone number per say... but thru a GPRS connection .
the avg speeds for a GPRS conection is about 64k. .. so your avg'ing home"dail up "speeds .. .. but it will work just about any where your phone works..
then there is phones with EDGE . basicly .. a faster version of GPRS. avg speeds with an EDGE connection is between 100k and 120k with faster bursts ... <rarely>
then there is the new 3G tech . avg speeds that i have seen are in the 1.2 mb range . and on a very consistant basis .
downside to this tech is the footprint is small right now... but if your lucky enough to live in a area that has it.. < DFW would be one.. > then you are the envy of a lot of geeks out there ...
the avg cost for unlimited uasge should be in the 19.99 range..
This is coming from a Cingular Sales rep . < me >
a while back i posted my drive from Dallas to Montarey Mexcio ... i had a live webcam going the whole way ..
linky its an archive link... so i think only team members can see it..
