I've searched other threads but nothing is helping me.

My curve is realllllly slow. I have to do at least five battery pulls a day. My free space is 24575225 bytes. I have a media card with a lot of pictures and ringtones, but none on the actual phone memory. Every time I get a new text, texts delete themselves from the bottom of the message list. I don't really understand why, seeing as I have so much free space.

It's really annoying. I have it set on save forever, and I used to be able to save texts for months, and then they all starting deleting themselves.

If it is a memory problem, this might help: How do I free up memory on my device? - BlackBerryFAQ

Really need some more info to diagnose it however.

How many programs do you have installed? 24M is actually pretty low for an 8330.

the only extra programs I have installed are the facebook app, beyond 160, & buzzme. everything else are just apps that came on the phone.
