What mobile technology do you use every day?

What technology products or services do you use every day?  What stuff could you not do without?  What brings you joy or makes your day easier?  What web services, software applications or gadgets light your fire, or just keep the fire from going out?  Nearly all of us have mobile phones now.  What do you do with yours?

The Mobile Applications I Can’t Do Without

It goes without saying, or at least it should, that my Blackberry Curve, Toshiba Laptop, and Sprint mobile broadband card top the list, and are in their own categories.

I use a Blackberry Curve 8310 on AT&T service, with multiple email addresses pumping correspondence into it. In addition to using the email, text messages and phone services, here are my can’t-do-without mobile applications:

Twitterberry – (Free) Developed by Orangatame Software, this applicaiton allows me easy and quick access to my Twitter account.  Twitterberry seems to be having issues loading large avatar photos with its latest release.  It can slog a user’s ability to quickly scroll through the updates of their followers.  Twitter uses Amazon Web Services for the hosting of images, but I’m not sure that’s the issue.  I don’t remember experiencing an issue with Twitter’s avatars or background during Amazon’s hosting outages last month.   Twitterberry also has a known issue with Twit Pic integration.  Known issue being a euphamisum for “something that’s busted and won’t be fixed today.”  Tiny Twitter is another application I have sampled, and did not enjoy.  Where Twitterberry limits the features it replicates on the handheld, Tiny Twitter goes overboard with too much functionality.  I’ll expand on the best ways to experience Twitter on a handheld device in a coming post.

Viigo – (Free) A mobile RSS reader.  I liked it before this newest release, and now I love it.  Among the features added was one for which I had pined: the ability to sync the RSS feeds I read with a web application.  Now I can manage my RSS feed reading from Google Reader through a web browser and it just feeds into the Viigo application on my handheld.

Google Sync – (Free) Crucial for managing and backing up my calendar, and keeping it at my fingertips.  Mine is setup with the Blackberry calendar as the primary, and it automatically syncs additions and changes on the handheld with my personal web-based Google calendar.

Google Maps – (Free) Working in concert with the Blackberry’s GPS feature, Google Maps helps me get to new places or places I forgot how to reach with ease.  It is not OnStar’s audio turn-by-turn navigation, but it is free.  You can view each step of the trip on a list, or on the map.  You show up as a little blue dot as you make your way.  Each turn is marked in yellow, and the final destination is red. Not that I’ve ever looked at it while driving.  That would be unsafe.

Remember the Milk (Free, but I use the Pro version for $25 a year) – RTM is a web-based task management service, a nice way to remember the things I have to do, like write this blog more often.  I can add new tasks via email, data entry into my handheld or a web browser, and even direct through Twitter if I wanted to. The Pro version I use allows me to sync the tasks between the web and mobile sides.

I also have a 2 GB SD memory card installed in the device for extra storage space.  This is the same type of memory card used in digital cameras, and is a very inexpensive storage option for BB users.  It installs under the battery, similar to how a SIM card is installed.

I am clearly addicted to my Blackberry, and all the many tools I’ve installed on it.  But I’m just one user.  How do you use mobile applications?
