I've had my 8320 for a while now, and its been working fine...
When im texting, after a few days for some reason all of the SMS text messages delete themselves. All email notifications still appear in the inbox but no SMS messages... I always have to do a hard reset with a battery pull in order to fix it. If i dont pull the battery, and i send another text, it will stay there for about 2 minutes, then delete itself again... It also prevent me from receiving.

Once i do a hard reset, everything works fine...
i used to have an 8300 and it never did this...
anyone know why my SMS messages will delete themselves?
i've gone a whole month without deleting my SMS messages on my other 8300 and it never had this happen...

If i go a week or maybe 2 if im lucky on my current 8320, it will do its automatic SMS delete, and i have to pull the battery and have it reset itself in order for it to fix.

ill check that link out right now

That's under 5 MB -- very low. That's definitely causing your problem. If you don't have a media card, I'd suggest getting one and moving all your pictures, music, ringtones to it.

i have a 2GB media card.
i think its because i have alot of apps.
all of my music, pics, ringtones are on my media card.

That will do it.

im at work at the moment.
i'm able to remove apps from the phone itself right?
to free up some memory?

Yes, follow the instructions carefully in that link I gave you.

Edit.. if you want to remove 3rd party apps, go to Options > Applications > highlight the app you want to delete, click Menu and you can delete there.

deleted a few apps.
got some more memory... hopefully this helps.
