[and what]

Hey
I'm having a major problem with my blackberry 7105t. Sometimes when someone text messages me, the new message icon will pop up for a half a second and then disappear and when I goto my messages ALL of them have been deleted as well as my call log. This is only happening part of the time, its very bizarre but im losing messages before even knowing i received them.

It seems as if they are erased before they're even viewed.

any suggestions??
