question bout upgrading

[rbboy]

greetings!

i presently have a
xda 1 here in the philippines
rom version: 3.14.17 ENG
radio version: 4.16
protocol version: 32S54

my question is, is it advisable or necessary to upgrade my rom version to the new version found at 02 official site? i already downloaded it but i haven't installed it yet.
i've learned in the forums the golden rule that DON'T TOUCH THE RADIO VERSION AS LONG AS IT WORKS. so i will not ask bout the radio version anymore.

please help me...thanks!

if you can extract the ROM upgrade files only, then it's OK to go to any WM2003 ROM

my device is only WM2002. does it matter? is it ok to upgrade the ROM to the latest version 3.20.06?

I upgraded mine last night - there are a few subtle differences.

ROM 3.20 is PPC2002 not a WM2003 ... you can upgrade to 4.01.16 if you still want WM2003 ROM

Once again, don't touch the RSU!! ... play with the ROM only :)

sorry guy's another question cause for everybody's info im just a newbie and i'm scared of messin up my phone. anyway, i've read problems with the synchronization or restoring data on the phone after upgrading the ROM here in the forums. will i just follow the steps given by myxda.com? or i really need to back up my ROM to an SD still?
sorry guys just wanna make sure. thanks!

it's strongly recommended to backup the current ROM to SD card ... I mean the backup option in the bootloader menu not the xbackup utility
