This week in iPhone apps took us back to basics with a traditional turn-by-turn navigation app, an extensive weather app, and a community based travel guide app.

MobileNavigator North America by Navigon AG has been long awaited by turn-by-turn navigation iPhone fans. This app charges a one time fee of $69.99 instead of requiring a regular subscription fee like other navigation apps have decided to charge. It comes preloaded with NAVTEQ’s latest maps and offers both 2-D and 3-D map views while driving.

CloudBurst by Advenio strives to become your one stop destination for all things weather. This app gives you the basics (current temperature, wind, visibility) well enough but it really shines with a current weather radar picture and four day forecast available on the same screen. And thanks to iPhone location you don’t even have to type out your zip code.

Keeping in the spirit of weather, Dopplr - The Social Atlas, by Dopplr brings the popular online Dopplr community to the iPhone. Dopplr is essentially a collaborative travel guide where users can recommend any new discoveries they made while traveling to the rest of the Dopplr community. With the Dopplr app for iPhone the worldly traveler can stay truly mobile as they explore new places and discover new attractions.
