Hi, I have an iPod touch 4th generation. I was thinking of purchasing this app Equalizer http://itunes.apple.com/us/app/equalizer/id321267949?mt=8 just to set all the levels at max in order to push the speaker louder as it is soft. I wonder whether this would hurt the speakers in any way. I may look for Cydia tweaks as well. I tried searching but I got no results about this issue. Thank you in advance for replying.
