Great!

PD maps is great! - ok the 3D-"Feature" is not usable but the rest is just perfect for iPod touch users!!!
Its the best app i know to download maps on your iPod touch/iPhone, since it is the only one I know where yu can chose from wich provider you would like to have your maps from (GoogleMaps, YahooMaps, OpenStreet, and more)!!
Premium User State is not that expensive - i recommend to buy it!
