I haven't seen this tip yet,I'm sure it's here somewhere, but hear it is.
Go to Media, Options and set the Reserved Pictures Memory to 0MB. I have a 2GB microSD card and store all my data on there.
Now what does that mean? It won't ever save pics to the phone, just always to the camera? Or what?
It's better to save everything on a SD anyway. If your BB goes down, you can just take the card out and put it in the new one. You'll still have all your ringtones, pictures and music.
