Hi,

I've never owned a smartphone before as I my employer won't allow camera phones on site (I work in the automotive sector with prototype vehicles) and I want to have a GPS with me when I head to South America later this year.

I've been doing a bit of research and I'm thinking of buying a phone to use then selling it when I get back. I'm trying to find out what good apps there are for travelers. Things of interest to me are GPS integrated city tours, PDF readers (for reading travel guide books), Spanish/Portuguese/English translation or phrase book apps. Anything like that.

I've yet to decide what type of phone or operating system to get, that will depend on software compatibility.

So, what apps are useful to travelers like us?

Thanks
