I usually do a battery pull to enhance my memory at about 10

4MB is low

I aim to have 15MB or more

I've had memory as low as 1 MB w/out loosing any functionality or messages/SMS, etc. I've actually never lost any data from my Pearl, regardless of the free memory reported. I have started to doubt the accuracy of the free memory reported...

I don't know if the 8100 is a lot different from the 8130, but the call problems you report don't seem like they would be caused by low memory...seem more like a network or hardware issue.

I always try to stay above 13MB

I tend to always be above 12MB... there are a few threads if you do a search for memory optimization. the one i really like is by John Clark

Did you use John Clark's memory optimization technique? If not, look in the General BB Forum here, it's one of the stickies -- "Losing call logs, SMS, emails? Optimize your BB ...."
