buy a m2 card reader (about3to4$ or less). place the m2 card in the reader and insert into m2 card port(moastly in laptops). if ur card is detected then it works fine and its ur phones problem .contact sony ericsson service centre. if ur phone is still in warranty then repairs will be free since its a software problem.
