How to add/remove music on IOS 5 without itunes?

About a year ago with my iPhone 4 I had a program installed on my computer that when I plugged my iphone in it would let me open the files in a windows explorer. (Same way you would view 'My Pictures' from My Computer). I could then add & remove songs from my phone without using itunes.

I have been advised that with the new iPhone 4S on IOS 5, that this ability has now been blocked.

Does anyone know a way around this? ITunes on my computer keeps freezing and is impossible to use (yes, I have the latest version). And when I do use it, it deletes music off my phone and adds random songs that I have not selected.

My goal is to not have to use itunes at all to view my music.
I don't want to use a similar program to itunes, I want to open it in it's own file.

Please, does anyone know how to do this?
Surely there's a way!

Verizon-no unlimited-will texting a iTouch with iMessage cost me?

I'm So CONFUSED…
i have the iPhone 4 on Verizon and i use iMessage and regular SMS. I have no unlimited texting WHICH MEANS i can text any Verizon phone for free but if i text any other carrier it is pulled into my 500 count.

SO if i text an iPod Touch user that uses iMessage will it get pulled into my 500 count? Cuz the iPod Touches don't have a carrier… So i don't know what to think.
