My Blackberry Pearl 8130 Keeps deleting the messages and calls in the call log?

It is not a problem with your device. It is designed to do that when the memory gets too full. See tutorial: 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.

My Blackberry Pearl is awesome and I got a fantastic deal when I bought it. There is a posting about the Blackberry Pearl over at this blog. http://www.mobile.123thebest.info/blackberry-pearl/ I would check it out.

How bizarre - do you pershaps have it set like that? Does it do this randomly during the day - when you sync it - or when you power it on/off?? There are a few websites that specifically have blackberry forums. You might want to try posting there. sorry I can't be of more help.
