iPhone Other Memory

[ReyZero]

Okay so I'm a little more confused about this other space that it's taking, and what exactly it's purpose is.

First off, I'm curious what everyone's at, I'm currently at 215mb of Other, and zero KB of free space, and everytime I clear up a little room, it goes straight into other.

Example, I was at 175mb of other, and zero KB of free space, deleted some useless songs and applications I don't use, and the other moved itself up to 200mb other, zero KB free, and I deleted more songs and applications and it moved to 215mb other and zero KB free.
I keep getting annoying messages on my iPhone telling me to re enter my voicemail password and others, and I know the simple thing is to delete a movie, but what the hell is going on with the other consuming everything, unless there's a lot of other it has pooling on the laptop waiting to put into the iPhone.

So, any input?
EDIT: My MobileSync in iTunes crashes when syncing the iPhone as well, which is getting annoying.

Edit 2: Seems it has stopped at 256.2mb other, leaving me with 3.1mb free. Hope I don't get anymore errors

Mine's somewhere around 350MB currently. I had 0kb of free space as well, yesterday, but I erased all music/videos from it in order to get some of my friend's music and copy it onto mine. 350MB is way too much for my liking, but a restore is just too complicated for me at the moment, so I'll have to wait til 3.0 comes out (I'm going to want the new features and it'll be worth the effort of a restore-then-rejailbreak-then-unlock).

I just reset my library, and I used to have 300ish, so I'm 50 under.
Case and point though, why was it growing, WHAT WAS GROWING FROM DELETING THINGS?!?!?!?
Just let me access the damn thing like a harddrive so I can delete useless crap :P
