Guess it depends what type of phone you have. I've got one of the Qtek Smartphones which has Internet Explorer on it so I can browse the Seabreeze graphs just as I would on my computer at home. Works a treat!
Plus because it is a web browser I can access any other sites as well including all the BOM stuff.

You only pay for the data you download; cost is 0.005 cents per K so it costs me few cents each time I look at the seabreeze site, but the plan I have includes about $30 worth of calls so I never have to pay anything extra.
