As we know Mac OS X 10.7 Lion Developer Preview 2 has been released. In terms of stability, Developer Preview 2 doesn’t improve much from the Developer Preview 1. It doesn’t feel like a Gold Master. It features refinements to an otherwise stable developer preview and also it includes bug fixes. Mac OS X 10.7 Lion Developer Preview 2 come with iChat account merge, redesigned iCal and more.
You can see from the image posted above which shows iCal has a new leather bound header (OMG) with faux stitching and the main window of iChat holds Bonjour, AIM, and Jabber contacts together just like Adium. If you are a registered member on Mac Developer Program then you can access the download.
