My phone has everything. If I could figure it out.....it probably microwaves a shore lunch for you! It has almost as good of a camera as my cheaper digitals, has the GPS with way points, has the recent photos I have taken of some fishing spots with the lake down, has music (don't use it for that much), it even makes phone calls. It does a ton of stuff that I have no clue about.
I also use mine for business a lot. I leave mine on vibrate too. No use messing up the calm and quiet of others while out in the paradise God made for us. Pretty amazing where the technology has taken us. I remember when people thought fishing with them thar fishfinders was cheating.
