AGREED! I'd be willing to shell out for this one too... Been pulling from Surfline Mobile if anyone wants to see what kind of data we are talking about (e.g. surf, swell detail, reports, wind, air/water temps, tides, wave models...)
Apparently Tide App is working on a free one for Blackberry. They say it's coming soon so hopefully we won't have to wait for long. I would like one as well.
