I Purchased 1GB micro-SD (TransFlash compatible) memory card from SanDisk, supplied with SD adapter. Since using the card in my Nokia 6233 the phone has become unstable and doing strange thinks. Eg listening to mp3 track from the card, then a electrical crackle and the display when blank. when the phone recovered it was as if i had just turned the phone on, with various settings back to their default. The phone will light up for no reason and not go back to its power saving display, killing the battery life. I have tried the phone with no card and with the card supplied from nokia and all is well.

Thanks in advance
