"If it were me" (well, it was me actually), I'd upgrade the currency mod from the 3rd party to the x-cart version of it first, then add the mobile mod after you get that working. Yes, they integrate together. Not saying it can't be done but it'll certainly make your life easier. The X-Multicurrency module is way cleaner and works better than that 3rd party mod (Ruby) I used to use anyway. That mod required TWO mods, one for geo tracking and one for currency conversion. The x-cart version is one package that does both.
