• Answer:

  It is NOT a glitch, they are designed to do that when they memory gets too full. See below: Symptom: Call Log Entries and Messages Auto Delete Due to Low Memory for a RIM BlackBerry Lost call log / Automatically deleted call log Lost SMS Text or e-mail Message / Automatically deleted SMS Text Message or e-mail BlackBerry Deletes Call Log BlackBerry Deletes, Deleted, or Deleting SMS or e-mail Cause: Cause 1 All RIM BlackBerry devices with handheld software version 4.2 or later utilize Low Memory Manager (LMM). Once the device memory reaches a threshold of 800kb or less, LMM will automatically remove data in order of importance to free up device memory. Once the device has reached full capacity, the device will not be able to store any new data such as SMS text, email, call log entries, etc. This is a list of the items which may be deleted: Low Priority: Delete attachment data, browser cache Medium Priority: Delete old calendar entries High Priority: Delete oldest e-mail messages NOTE: Saved messages will not be deleted. This list is not complete as there may be other items such as SMS text or call log entries which may be deleted. Cause 2 Switching between two applications on the device using ALT+ESC approximately 25 times will cause a memory leak. From this point on, switching applications on the device will cause an hourglass to appear for an extended period of time, which causes a large decrease in memory on the device. There is no ETA for resolution at this time. Fix: If the BlackBerry device becomes low on memory, perform the following Check the available memory on the RIM BlackBerry. Configure application options to reduce device memory used: Configure Calendar options to keep appointments 60 Days or less. Configure Call Logging options to Missed Calls or None. Configure Media options for "Device Memory Limit" and "Reserved Picture Memory". Configure Message options to keep messages 30 Days or less. Configure Picture options to "Store Pictures" to On Media Card. Clear the browser cache and cookies. Transfer media files from the device to the computer. Delete media files, such as music, pictures, ringtones, or video Uninstall or remove programs that are not used often, such as games or third-party applications.
