I'm no techo but I did look into this quite a bit. I access the SeaBreeze site via GPRS and it works well, and average cost to check the wind speed is under 40 cents. From my understanding you can get GPRS/WAP wherever you can get mobile coverage-and so far I've never had a problem anywhere unless SeaBreeze is offline.
From my understanding, WAP charges the user via time connected, whereas GPRS charges via Kb of data downloaded. The phone companies want us all to connect to GPRS and stay permanently connected so at any time you can see the current data - your phone will automatically keep updating. I just turn it on when I want the info then disconnect.
I contacted the Bureau of Meteorology and requested their forecasts be made available via WAP/GPRS. They replied that because they are a Govt Dept, they are unable to provide information to us taxpayers free if there are commercial providers providing the same service-apparently they can't give you something if a private concern is selling it to you. As there are a few people who will SMS you the weather forecasts (for an ongoing fee), so BOM won't provide. I replied that's nonsense because I can get the forecast for free off the net now, so why not get same forecast via WAP/GPRS ? No reply.
Anyway, your choices are to pay someone to SMS updated weather to you (expensive), or we all beg SeaBreeze to add the forecast to the WAP section. How about it Laurie - can it be done ?
