Yes. The first two are at &t and will cost you money
The second two are google, free and very useful .
I usually start in maps. From maps you have lots of options. One thing you can do from maps its ask for directions, which launches navigation.
By the way maps works fairly well with just the data connection, no satellite gps, and chews up about 5 megabytes per hour. Navigation requires satellite gps which will devour your battery and sometimes doesn't lock in well.
In summary, start in maps...it does almost everything you'll need and does it well.
