I've been a memory map user for years with maps on my PC. When I bought an iphone I had to buy the £20 version of the app to use existing maps on it.
I've now got an ipad too. They have now done away with the paid for version of the app but it still says you can use and transfer your maps to it from your PC. I've transfered the maps using Itunes but the app is banging on about a 5 day temp licence. Is there more to it?
I'd look at the website but it seems to be down once you get past the shop front.
