Summer in Europe!

[Swiggy]

I will be back packing through Europe this summer and will have no data enabled phone. I want to still utilize my HTC Hero though.

So I am looking for apps that will work with just WIFI or NO data/gps connections.

Apps In particular that I need:
Translator that works with no wifi/internet (will be in Prague/Spain/Germany)
Map app (that works with no data/gps)
Currency converter
A good photo app that will let me keep notes on pictures

Wifi only apps that will be useful when traveling:
I have Fring so far...

Any suggestions would be great!
