Yesterday, AT&T began selling the HTC Inspire 4G. The Inspire features a massive 4.3” super LED display – the largest of any phone on AT&T’s network – and runs the latest iteration of the HTC Sense UI, all for $99 (after a 2-year agreement). It also marks a number of firsts for AT&T:

• It is the first 4G phone on their network
• It is the first device to run Android 2.2 on AT&T
• It is the first device to make use of the new Mobile Hotspot application

The HTC Inspire brings an impressive list of features that are sure to be a hit among new phone buyers. I could dedicate an entire post just to those features. However, I’d like to focus on one specific feature: 4G. With the increasing amount of work done on while the go, the speed of your mobile device’s wireless connection becomes more and more important.

As I was writing this post, I decided to run a speed test on my 3G device. The result? I got a little over 1mbps down. To put that in perspective, most home internet connections are at least 10x faster. For downloading a small document or photo, 1mbps is does just fine. However, when downloading large documents with charts and graphics or high-resolution photos for work, you’ll often find yourself waiting for as long as a few minutes, depending on your signal quality. It may not seem like much, but over time it adds up and eats away at your productivity.

The obvious question in all of this is, of course, what does 4G mean when compared to 3G? The answer depends on whom you ask. At the end of the day, “4G” is merely a label. What it really means is that mobile data connection speeds are constantly improving – and when your mobile productivity relies on the ability to access data quickly, that is what truly matters!
