sun,moon & tide

I am about to get my self a HTC desire at the end of May when I can upgrade my phone.
I do photography for an hobby and use Nikon gear, I would like to find an app that would tell you the state of tide in a graph form for the coast that I am nearest to, and the ability to show tide times for future date to any part of the coast in any country, this could be done using GPS.

Plus Using GPS, and Compas and if posible the camera on the phone show ware and when the sun and moon will rise and set on any given date on the horizon, using augmented reality.
This would be a realy usfull tool for photogrpher, especialy when visiting places they have not been before or to plan the right time and date to get that perfect shot.
is there any thing like this on the market.

You might wanna try Google Sky Map,

I do not think it will give you the tidal conditions, but should give you the position of the sun and moon.

I second Jeremiah's suggestion -- it's a v. cool app.
