Google's gone ahead and uncorked the bubbly to celebrate the launch of Android 2.0 "Eclair" today ahead of Verizon's big reveal tomorrow, bundling its announcements into two very important sections: SDK support, meaning devs can go ahead and start targeting the new bits, and a comprehensive list of changes in the latest version. Here are the major changes us lay folk are going to care about:

• Support for multiple Google and Exchange accounts
• Third-party "sync adapters" allow apps to tie in to the phone's sync services
• Quick contact menus for fast access to specific key pieces of contact information
• Unified email inbox (yes!)
• SMS and MMS search
• Text message auto-delete after a user-defined thread size is reached
• Significantly improved camera controls with white balance, macro, effects, and more
• Improved keyboard layout, dictionary, and algorithm based on multi-touch support
• Double-tap zoom in browser, support for HTML5
• Bluetooth 2.1 support with addition of OPP and PBAP profiles
• "Better" graphics hardware acceleration

Needless to say, we're extremely excited about the changes Google's made here -- and on top of the Droid, we can only hope this action is coming to legacy devices on the double. We'll find out soon enough (hopefully).
