What eats up the most application memory?

Ok, so I just got a blackberry and have read many of the threads concerning how to optimize the blackberry. I've only installed a few apps, nothing big yet out of the 128 megabytes of application memory, I only have 12 or so free. I've moved things into folders, deleted unnessary apps, tried everything. I have almost no third party apps, i deleted yahoo messenger, i have a media card for pictures, etc. What could it be that is taking up so much memory? Do saved voicemails take away application memory? Contacts? Any help would be appreciated

The is itself uses up 100 mb or so. The first time my Storm was booted after upgrading to OS five I onlj had about 24 free mb, and after installing ten apps or so and letting the caches build up I only have 16mb from boot and 5 mb after a few days.

Anything with a memory leak, themes or apps.

its just a benefit of owning a storm 1 u only gunna have between 10-30 free depending on how many apps and how long you leave your phone without doing a battery pull or using quicklaunch
