I found a way to access the iPhone 2.0 Firmware in advance of the official release through iTunes. I decided to give the upgrade a try and liveblog it on Twitter. You can see the transcript of this on twitter.com/daiello.

I had complete success with the installation. I was able to install Epocrates Rx, Twitterific, and Evernote. The preceding links are to screenshots of each application on my Flickr account.

The most interesting feature addition I've found in the iPhone 2.0 firmware is in the Calendar. Calendar now shows which iCal calendar each event comes from. Here's a screenshot I posted to my Flickr account that illustrates this feature.

I would provide details on how to perform the 2.0 Firmware update yourself, but Apple has asked other websites to take down the information that they previously provided about where to get the firmware image. I have no interest in repeating information that Apple is actively trying to quash.
