Gingerbread has Got some awesome features.

Gingerbread gets your android to compete with other smartphones more fiercely.

New Keyboard
First of all, the thing that everyone uses every freaking day of the year, the Keyboard. This new keyboard has its keys reshaped for faster input and editing, bringing up word suggestions also depending on what letters you’re typing. Switching to voice mode allows you not to replace selections, multi-touch key-chording allowing you to type numbers and symbols with keyboard shortcut combos instead of flipping back and forth like you’ve got to now. Included deep inside the keyboard class “android.view.KeyEvent” is support for the following buttons – A,B,C, L1, L2, R1, R2, select, start, X, Y, and Z – aka PlayStation controls.

Copy/Paste
The copy and paste function has been improved to include pressing and holding to select words, stay in selection mode, and copy text for later pasting. Along with this is:

Word Selection
Improvements to word selecting include the aforementioned press-hold, a function iphone users are already used to using. Once pressed and held, a free-selection mode begins, a place where you can adjust the area you’re selecting by expanding bounding boxes.type efficiently and easily with gingerbread.

Power Management
Improved next is your ability to manage your power usage. Inside your application settings, you’re able to see your battery in how it’s being used by various apps. See how much that Matrix screensaver really is sucking up all your juice! Hopefully soon those task killers will be rendered outdated.

Application Control (Task Killer Killer)
Along these same lines is a shortcut to “Manage Applications” which you can reach in your options menu. From here, you can indeed view all of your applications, how much power they’re using, and you’ve got the ability to stop any app instantly.

NFC Near Field Communication
This is the future of commerce as far as credit cards go. Use this to touch or swipe NFC tag embedded posters, advertisements, other weird junk, to be directed to a website (and more than likely other such actions). In the future, this functionality will work to send and receive money via your handheld device. Excellence.

Internet Calling
SIP Internet Calling addresses can be added to your contacts list and you can make internet calls via Quick Contact or Dialer. Hooray! Of course you’ll need a SIP account for this to work and these features will be turned off or on depending on what your manufacturer or carrier wants.

Downloads Management
A new download manager is in place to work from your browser, email, or other apps. This could be rather helpful I must say so myself.

Camera
Multiple Cameras can now be accessed from your one new camera app, just by clicking the “select camera” button.

UI Improvements
Simple changes in the user interface of this Gingerbread system make the whole situation faster, easier, and more power-efficient. One example is the changing of the background to BLACK in the areas that it’ll always be covered up such as the notification bar, menus, and etc. Changes in these menus are also in place to simplify.

Developer features

1. Native development. The ability to write Android programs or parts of programs isn’t new but in Android 2.3 it gets a huge boost with Release 5 of the Native Development Kit (NDK). For example you can now receive input and sensor events, produce sound, manipulate 3D graphics contexts, access assets and storage, and more all from native code. They even added a NativeActivity class that lets you write your lifecycle callbacks in native code.
2. JVM speed. For Java developers, 2.3 adds a number of speedups, most notably a concurrent garbage collector. According to Google garbage collection pauses will be under 3ms, which is small enough not to be noticed in a 30fps or even 60fps game. New JIT optimizations make Dalvik code run even faster than before.
3. Faster event distribution. In previous versions of Android, just holding your finger down on the screen would cause whatever program was running to slow down, sometimes dramatically. This is all fixed in Android 2.3.
4. Multimedia. Rich audio effects like reverb and headphone virtualization can be applied to local tracks or globally across multiple tracks. The platform adds built-in support for VP8/WebM video, plus AAC and AMR wideband encoding. Also, there are now official APIs for accessing the front and rear cameras. There is some limited support for extra large (tablet and TV) displays.
5. Near Field Communications (NFC). In Japan, NFC is a Big Deal, and the hope is that it will catch on in the rest of the world too. It has all kinds of uses, for example with the right hardware and software you could use your phone as a replacement for your credit card to make point of sale purchases. Using the NFC API apps can respond to NFC tags embedded in stockers, posters, and even other devices.

Android 2.3 has got many awesome Reasons to update your phone to it,if you have an update ready.
