The very interesting LG Optimus GT540 has finally received the official Android 2.1 update from LG. The update from 1.6 to 2.1 is relatively painless and it shouldn't take too long until you're enjoying all of the features Android 2.1 has to offer.
The upgrade will enable the following features:
Android Eclair (2.1)
Quick Contacts Interface
HTML5 Support in Browser
Microsoft Exchange Support
Bluetooth 2.1 Support
