i thought i'd compare with some friends overseas, see what the price of data is
here in NZ, GPRS casual rate is 10c/10kbyte.
you can purchase a tiny 3MB/month for $10
through to a more reasonable 250MB/month for $150.00

compare to the US, unlimited GPRS is available from several telcos for US$20/month
unlimited EDGE from at least one telco for US$80/month
unlimited CDMA data from sprint is US$15
of those i asked, no-one knew the casual rate, because it's cheap enough that you might as well go unlimited.
What are other people paying for mobile data???
