That is a great App for the Touch. Downloaded it today but had a bit of an issue getting caches into the database. Not the apps fault, mine.
We load the caches from GSAK. Export a GPX file ver 1.0 then email it to ourselves. The issue here is what to use as an email account. Hotmail DID NOT work. We set up a Yahoo account and Yahoo mail works perfectly. The caches d/l into the database and away you go. Nice easy interface and really simple to understand. Must be really nice on the iPhone.
Great recommendation TS.
