does anyone know of a procedure to unlock this phone from its vodafone network, i have tried using a unlock chip and ICC code that did not work, any ideas? i need to use it with a new o2 sim card

Sounds like you are in the UK from network carriers you mention. Vodafone is the most troublesome and/or expensive carrier to get unlocked..either you may wait for 30/35 days unlocking time or you’ll have to go for the most expensive express unlock service. Both services are available at various sellers on eBay at about 15£ for the cheaper one or abt 30£ for express service.

Hope this helps to you: https://www.youtube.com/watch?v=E0KpqwsB
