Android rooting...

Why root your Android
phone/tablet?
The main reason people root their
Android device is for freedom and
control, and when you root your
Android phone or tablet you gain
full control over your system and
can tweak it to your liking.
Improved performance: You can
speed up your Android device by
relocating your phone’s cache, thus
allowing you to save phone
memory and have a faster phone.
There are applications available in
the Android Market that will allow
you to overclock your device to
make it go as fast as you dare.
Altering system files: You can
replace many parts of the “Android
core.” Doing so, you can add new
themes, edit the core apps (Maps,
Calendar, clock, etc.), change the
recovery and boot images, add
Linux binaries, and many more.
More application choices: You will
be able to install apps that are only
compatible with rooted phones.
For instance, you can install an app
for taking a screenshot of your
phone, or for overclocking your
device, or for tethering.
Install applications to your SD
card: One of the most talked-about
feature (or disadvantage) of any
Android device is the limitation
where you can install applications
only in the phone’s internal
memory and not the SD card.
While Google may reason that SD
cards are slower in general and
cannot run apps as effectively as
internal memory, the fact of the
matter is that most Android
devices do not come with massive
internal storage and, hence, greatly
limit the number of applications
that can be installed at a time.
With rooted devices, you can use
Apps2SD, which will copy ALL your
applications to an ext2/3/4
formatted SD card and will also
store future builds in the card.
That is freedom to choose.
Latest Android OS (operating
system): With many carriers
holding back the updates to the
latest Android operating system,
rooting your device will give you
the option to install any current
and future OS’s by installing
custom-tailored ROMs.
Wi-Fi and Bluetooth Tethering:
After having rooted your device,
you can also use Wi-Fi or Bluetooth
tethering to share your cellular
data connection with your laptop,
PC, or other capable mobile
devices. The application works with
ad hoc connections and will get
you up and running online on your
laptop in no time. Similarly,
tethering can also be achieved over
a Bluetooth connection.
