sprint setup info

[niw559]

when i first got my sprint phone(apache) in the mail i had to insert a bunch of codes that an operator gave me. if i do a hard reset/ flash the rom will i need to know those codes or any other pins?

i know with cingular/att and the mpx 220 that wasnt an issue maybe because they use sim cards.

any help would be appreciated as i want to put WM6 on my apache. seen something about gps setting i didnt think this phone had gps???
