I've had trouble getting my k850 to connect to the internet on Tmobile US, every time I send myself any settings or manually type them in, the phone does not accept the settings and automatically turns them off. I've called Tmo, they've told me that this is a software problem and that I should talk with Sony Ericsson. I did, and the only conclusion that we've come to, was that the phone must be reflashed. He told me to use EMMA, or some other software because repair would cost $100. I'm not exactly sure how to use EMMA (or where to find it), and I don't think that there is any free program like XS++ that supports db3150... Does anyone know about this kind of stuff?
Have you tried the Sony Ericsson update service?
If not you can use any online flasher.
