After an upgrade to the oh-so long awaited iPhone OS 3.0, I finally decided it was about time I wrote a little list over the apps I use daily, and that I would recommend people try out.

Note that these are just applications that are of use to me personally, and you might think they’re not applications you would have any use of But then again, that’s not what this list is for.

1. Twitfire

Twitfire is a very simplistic Twitter client. It’s made just for posting tweets, and that’s it! I figured, instead of having 3 or for twitter clients that does an ok job, reading and posting. I’d have one client that does one thing, and does it well.

With this app you can post pictures that get automatically shortened with in.ex twitpic, update your twitter location data, and add a link to your current location in google maps, and you can also post the usual @replies,  URL links, hash tags and so on.

2. Facebook

Can’t go wrong with a good Facebook client. This client does exactly what it’s supposed to. You can read latest updates, update your status, brows profiles and upload pictures. All within the app.

3. Runkeeper Pro/Free

Well, now for some non-social related apps. This app is by far one of the best runtracking apps available at the moment. It’s simplistic, low battery consumption, supports playing music while used and uploads statistics to the net for your own personal statistics.

So far I’ve used it about 3 times, as I’ve really wanted to get in better shape. And every time I’ve received a perfect placement on the google maps for where I walked, how fast I walked, how many calories I’ve burned and so on.

On this page http://bit.ly/13yogv you can find a trek and see how it looks after a walk from down town and home.

4. SHOUTcast

This little app enables you to stream any radion from the shoutcast directory, directly to your phone. Either through WI-Fi, or 3G (probably also on Edge, but it’s not recommended). The quality is superb, and the selection of music is very good.

5. Bussorakelet

Now here’s an app that probably isn’t for that many of you, but it’s very useful for us living in Trondheim. It’s an app that enables you to query the time tables for the local bus transit called the bus oracle. This simply asks the busoracle on http://www.team-trafikk.no and gives you the results directly in the app. It lacks several features in my opinion, like for example the possibility of having pre-defined questions, but it’s good for when you’re in town and wonder when the bus will be leaving.

I’d say it also beats having that big wad of paper with you with all the different buss routes.

I will probably make more of these posts as I come across apps that I find useful. There will no doubt be changes to this list, once the push notification system for the iPhone OS 3.0 is up and running with all the new updated apps that are coming out.

(P.S: All the logos are links that go directly to the iTunes application.)
