Better performance, A little better theme than 1.6, better touch response, better battery life, access to Android 2.x only apps, somewhat improved bluetooth, live wallpaper and few more..
Is it possible to make a decent backup/flash backup of the branded stuff that comes with my phone? If yes how could I achieve this?
Root your phone and use titanium backup..
If it's possible to safely backup (to be able to keep waranty intact somewhat) can I get the upgrade for 2.1 NOW? Because I still don't have it (slow ass T-Mobile doing it by serial number or something)
You can back up normal data (and also apps from market in android 2.1) like contacts, messages, settings etc through Se back and restore utility.
For backing up system apps, or upgrading to 2.1 out of turn, you need to root your phone, that will theoretically void your warranty.
Rooting, is it a good idea? What can I achieve with rooting my device (I know it gives me root access but what can I do further if I have root access?)
Wonderful idea, only if you are familiar with system tweaking and somewhat familiar with linux. And you are willing to take risks.
for example -
a) You can simply install some very useful root only apps like titanium backup, root explorer, app2sd etc to manage your phone contents.
risk associated: very low to moderate
b) you can even change basic framework and theme of your phone, remove bloatware that comes with phone and use terminal emulator to have (almost) full fledged linux console. etc
risk associated: Moderate to High
c) When it comes out, you can even get custom roms on your phone
risk associated: Very high to Fatal
If I ever brick my device, is it still possible to get the original firmware on it?
Depends on how bad the phone is messed up, at the end all depends on your knowledge of using the right methods and right tools.
If you can get the phone to recognized by SEUS/PC Companian/Flash tool you can (hopefully) repair/reflash it with firmware.
Hope it helps..
