you are much obliged, and personally i wouldn't remove them... just because if you don't use them they never run anyway and they take up such little space. i use DSP manager for music, but not the Development tools, but every once in a while i go through my applications and processes to see what's running and what's not and the Development app NEVER runs unless you start it i've noticed, but like i said personally i think DSP manager is worth having on the phone, but tha's just my opinion, and same thing with the DSP app is i've noticed if you never use it then it NEVER runs.
