Will Re-Flashing Vodafone Live T610 remove WAP/GPRS settings?

Hi,

Recently upgraded from my trusty R520 to the T610 with the really
awful Vodafone Live menus and stuff. I'm keen on reflashing it to get
back the SE look but was wondering if by reflashing, will it remove
all the WAP/GPRS settings for Vodafone Live (I use vodafone, and would
like to keep these if possible since I use GPRS and WAP a lot)?

Someone who has had his/her T610 flashed back to original SE
settings/look let me know please. If not, guess I'll have to try to
take down exactly what customisation settings I need for WAP/GPRS (or
is there a website somewhere which shows these details? I remembered
how big a mess it was trying to set up my R520!)

TIA
