Ive bought a Nokia C3 locked to Vodafone. Ive remote unlocked it so I can use it with Pay&go O2 Sim Card.

Ive just found out that I cant use O2 Wap because Vodafone have locked the Wap settings on their Firmware.

Do I need to Debrand? How hard is it? What Do I need and where do I get the Debrand Firmware?

cheers for any help.
