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:confused:. 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........
