Most people who’ve been in the mobile industry for a while are used to the old Mobile Web service vs Application argument. Which is better? Which is wider reaching? Which is cheaper to develop? Which is more powerful?

It’s generally accepted that an Application is usually faster, better looking and can be more feature rich as some device hardware can’t be accessed from within the browser.

When it comes to Twitter applications on mobile devices, a native Application is the clear choice. The UI is generally awesome, you can have extra features such as TwitPic support and location support, and you can leave it running in the background so it can alert you to new tweets, DMs and/or @replies. When it comes to Twitter Applications the browser should lose hands down.

However, when it comes to the iPhone, things are a little different. There are, of course, a bunch of great Twitter applications for the iPhone avialable through the App Store. Most of them are free and have all the features a Twitter-Fanatic will need. The problem is that the iPhone doesn’t allow for Multi-Tasking so none of these applications, as great as they may be, can run in the background.

Why is this a problem? Well if you want to do anything else with your iPhone like check your email or make a call, you have to exit the application. You then have to reload the application again when you want to check your tweets which can take a few minutes at start-up.

Enter Dabr, by far the best web based Twitter application for any mobile phone. It comes as feature filled as is possible from within a browser and looks clean. You can check your replies, search, follow, unfollow, favourite, re-tweet and everything else. In fact the only thing it can’t do is post Twitpics (but can on a handful of devices) and geo-tags, which is down to browser constraints. Take a look, you certainly won’t regret it.

So why choose this Browser application over Twitterific or Twinkle? Simple – The browser is one of the few native applications on the iPhone that *can* multi-task. Within the browser you can run up to 8 tabs simultaneously which allows me to check my email while my tweets are loading up or read a news story (Note: I know Twitterific and others can open links within its own browser but you can’t open pages you want to visit from that ‘browser’. It’s not the same thing). Also if I want to do things like make a call or run another application the Browser stays running in the background and re-loads again as soon as I open it up. Sure it isn’t true multi-tasking like you get on Symbian and other devices but it’s as close as I can get on the iPhone.

The other advantages are that Dabr is totally AD free, unlike some of the Free iPhone Applications. It’s also a lot quicker when refreshing that the native Apps. But if all that wasn’t enough there is another great reason to use Dabr. The developer behind it, @davidcarrington, is great at responding to user requests within days and ever a few hours in some cases. Just send your requests to @dabr on twitter and you’ll be heard
