This is a "how
to" on unbranding or getting rid of the Cingular/at&t junk on your
phone. Should work for other carriers as well.
The benefits to Unbranding are:
-More RAM for multitasking/web functions
-ability to select network, which can save battery life
-ability to install programs not normally allowed by Cingular.
-some button changes, giving you more flexibility.
If you try this, you do it at your own risk of bricking your phone. You've been warned!
