X-Road Co.’s G-Map US West and G Map US East were released back into the app store in January. However, the new updates to these applications feature TURN BY TURN GPS on the iPhone at last. Each app which is 800-900MB applications cost $19.99 and feature western and eastern maps for the US, with Europe coming soon. BUT WAIT! You may be surprised about the size of each application, but the maps are stored on the iPhone itself, which then preserves battery life by not needing to use 3G speed to load maps. Apple somehow let this one slip, so go get it before it’s pulled off!
