Aren't your user agreements with your carrier? I've seen Debian installed on Nokia phones, but you still need a carrier so you can use the phone. Geez, you remind me of how I felt just before I wiped Windows off of my laptop.

i know the carrier thing, they just overwrite protocols as "true" "false"(it's a third party company that represent nokia in my country...)
numbers and id's(basically the "sim" i want to see if they can be put in manually, anyway i know the os+kernel(whatever it's called in a mobile) probably is burned straight on to the phone,so what i was thinking of wiping out what can be discarded and mounting over something from like the debian genre.
i personally change much of the rules in the phone every time i get it back from a repair,but the security still su*ks and agreement terms in my opinion should be illegal,they intercept all data,view all contacts,and sell all the info for publicity reason's.and then MY friends get Spam!

GionEasy9 is correct. But if you still want to WIPE OUT EVERYTHING then port Android or Meego on your phone
