Thanks for your reply but I have fallen into the seus trap and updated the firmware,because I began to panic,bad move. I realised what i had done when i searched further. The phone is now working but is now a cid53 :(.
Is it still possible to unlock this phone without having to go to the service provider for the code? If it is possible could someone please point me in the right direction to do so e.g what tools to use and a suitable tutorial re cid53?
Thanks.

To all those out there Please,Please, Please be aware of the Sony Ericsson Update Service and the possibilty of it making your phones firmware CID53 which appears at the momment harder to work with.

Any way the question remains can the unlock still be done?
Thanks.
