I get this message quite often and the only way to fix it is to remove the battery and reboot. When i get this message im trying to play ringtones or music and the phone sounds do no work.

I just got the curve 8330 today and have seen that msg a few times when trying to download larger apps. I thought it was simply because the network for Boost is slower than death??

my apologies it was media processor is busy. The only way to resolve this issue is to remove the battery. This is very aggravating alone but i also have the otterbox case and holster which makes it even worse.
