Believe it or not.I bought this phone and after a perfectly valid operation with the USB cable, this phone competely went dead.The saving grace was the excellent customer service and the prompt replacement phone i got.Since I wanted to alter the ring tone to be able to differentiate this phone from the other similar phones around me, I tried using the USB cable again. The phone software just hung this time and now I only get a Sony Ericsson Logo on the screen.As a phone with all the bells and whistles, it is very nice only if the software that it uses was better programmed.I am not sure what kind of response I will get from the customer service this time but I do hope they remain ever courteous and do the needfulIn short, NOT RECOMMENDED FOR SERIOUS USE.
