Thanks to Apple’s insistence on using the almost comically vague “Bug fixes” in its descriptions for incremental iPhone updates it’s hard to know exactly what has been fixed until people have a chance to try it. The hope was that today’s software update 2.0.2 would correct the 3G connection issues some people have been having.

The problem with me trying it out myself is that I have not been having issues with the service here in San Francisco. I did, however, have major issues with I was in Las Vegas this weekend. So relying on 3rd party reports, there are people in the Apple Support Forums suggesting the update didn’t fix the connection, but there are also conflicting reports on the same forum.

However, the video below, put together by the team at iPhone Buzz, an iPhone-focused blog, shows a side-by-side comparison of iPhone software 2.0.1 versus 2.0.2. The result? 2.0.2 absolutely demolishes 2.0.1 in terms of 3G connection speed.

It’s notable that sites loaded almost identically on the Wi-Fi connection test on both phones, and multiple tests are done on the 3G connection, so it doesn’t appear that this speed increase is an anomaly. Watch for yourself below.
