1. Get extra calling power by integrating Google Voice into your phone. Once you've signed up for an account, download the official app and watch your options expand. Bonus tip: Add the Google Voice widget to your home screen for one-touch toggling of your outgoing-call preferences.
2. You can send text messages for free through Google Voice--everything you need is in the app. Just make sure you change the settings to refresh every 5 minutes so that incoming messages won't be delayed. If you want faster notifications, log in to the Google Voice Website and configure your account to send you e-mail alerts when a new text arrives.
3. Get unbilled talk time by using Fring, a free mobile chat client for Android. Fring lets you make calls over Google Talk, Skype, and any SIP calling service.
4. Cut down on calling headaches by using the free Dial Zero app to call the companies you do business with. It lets you bypass annoying phone trees and get right to human representatives.
5. Keep annoying callers away by routing them directly to your voicemail. First, open the offending person's profile in your contacts list. Then, press the Menu button, tap Options, and check the Incoming calls box.
6. The Incoming Calls screen also holds the option for setting custom ringtones for callers. TapRingtone and change each person's tune as you wish.
7. Want to use your own MP3 files as ringtones? No problem: Make a new folder on your memory card and name it ringtones. Copy your MP3s there, and they will automatically show up in your selection list. Folders called alarms or notifications will do the same thing for those respective functions.
8. Check out the free app RingDroid. With it, you can easily edit an MP3 file to grab a precise segment of a song for a ringtone or system sound.
9. Android lets you keep multiple browser windows open at the same time. Long-press any Web link to open it in a new window. Tap the Menu key while in the browser to toggle between windows.
10. Prefer seeing Web pages in landscape mode? You can tell Android to always display sites that way. Select the Landscape-only display checkbox in the browser's Settings menu.
11. Android's built-in browser isn't your only option. Try Dolphin Browser for cool features such as tabbed browsing, gesture-driven commands, and multitouch zooming (yes, even on the Droid).
