Review: LG Nitro HD for AT&T
The LG Nitro HD uses the stock Android phone software, though it has been skinned by LG so it looks a bit different. The phone application is simple and straightforward.
The phone app includes the contact database, which is accessible via one of the tabs at the top of the screen. There aren't any nifty contacts widgets, but at least you can add shortcuts to your favorite contacts to the home screen, as well as add them to a folder of favorites that is visible from the phone application.
As with all Android 2.3 devices, it adds details from Facebook and other accounts to your contact database and keeps everything synced.
