every now and then my sms's seem to delete themeselves and i have no idea why ive been in the settings and cant find anything reason for it, sometimes they will store for a few weeks and delete and then sometimes they are only there a day and then delete themselves
That was the same thing that my phone did I have a blackberry Pearl 8130 and when I go back to my messages it delete itself so what you have to do is delet some stuff off your phone or get a memory card.
