I had the same issue before. I brought the phone back to the shop where I had bought it, and they said they had to send it to the repair place. The next day I got a phone call telling me that my phone had to be sent to Sony Ericsson to be repaired. 3 weeks later, a brand new Sony Ericsson W580i arrived. I am having loads of issues with the new phone. It is the worst phone I've ever had. Lucky, my contract is up in 1 month, and I'm changing it, never to go back to Sony Ericsson again
