This is almost a must have for individuals that want navigation without the network-dependency: MapDroid!

Thanks to this software, you can use your Tab as an offline map viewer. It features an inbuilt map repository browser for easy downloading, and features like rotation and 3D for comfortable browsing.

I'll likely get this software. The speed alone is worth consideration than pulling maps from the network via 3G, not to mention the cost.
