(Hi guys im new to this forum and topic... let me share my experience.

I bought a new K800i phone from dubai. I am living in India. It was an Orange branded phone. I first played with accoustic files and changed it using xs++ so that sound increased. Also my CID 51 was updated to CID 52. Then i thought of updating my firmware. I used sony ericsson update service to update my phone. everything went fine and update was success. but my phone got sim locked. It now says Insert correct sim. Any advice to me????? Please dear friends tell me a solution... How can i unlock it? What is the concept of patch unlocking??? please reply please........ )
